At first glance, the way the Apache mod_rewrite module handles query strings can be a little intimidating. mod_rewrite works by sitting on your server in a file called htaccess, and “catching” requests for URL‘s. It then checks these URL request against a series of rules and conditions you have set. If the request meets any of the rules and conditions, it applies then necessary changes to the URL, then reprocesses the request with the changes you have directed. Read more – ‘Apache RewriteRule and query strings’.

Setting an Expires (or Cache-Control) header in Apache will help speed up your website. I'm running Apache 2.x, and define an expires header for all of the site's static assets (images, stylesheets, and scripts). Read more – ‘How to Set an Expires Header in Apache’.
Before Ant, building and deploying web applications required a series of scripts or manual processes, which often led to mistakes. Apache Ant is a software tool for automating software build processes. It is similar to Make but is implemented using the Java language, requires the Java platform, and is best suited to building Java projects. However, that doesn’t mean it is restricted to Java projects. I use Ant increasingly for all my web development projects as it is an integral part of Eclipse, my IDE of choice. It makes building applications and releasing them across different servers far more efficient and less problematic. Read more – ‘Apache Ant Best Practices’.
Take control of your code with these programming best practices from Kevlin Henney.

PCI DSS stands for Payment Card Industry Data Security Standard, and is a worldwide security standard assembled by the Payment Card Industry Security Standards Council (PCI SSC). The PCI security standards are technical and operational requirements that were created to help organizations that process card payments prevent credit card fraud, hacking and various other security vulnerabilities and threats. The standards apply to all organizations that store, process or transmit cardholder data – with guidance for software developers and manufacturers of applications and devices used in those transactions. A company processing, storing, or transmitting cardholder data must be PCI DSS compliant. Read more – ‘Secure Your Application – PCI DSS Specifications’.
ColdFusion is 13 years old. That make makes it the daddy of the web world! It does not make it any less hip or useful than the relatively new kids on the block. Let's not dilly-dally, bicker or insult one another about which is best, which one is dying and which one is not worth the computer it is compiled on. What is important is to understand the merits of each language and decide which one best suits the application, not only in technical terms, but also in terms of time-to-market, cost of development, availability of a skilled workforce etc. Read more – ‘Let's not Dilly-Dally: ColdFusion has its Merits’.
If you're currently not using Eclipse as your development tool of choice, you certainly should be! Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle.

An increasingly popular technique among websites and in particular, blogs, is the idea of making URLs search engine friendly, or safe, on the premise that doing so will help search engine optimisation. By removing the obscure query string element of a URL and replacing it with keyword rich alternatives, not only makes it more readable for a human being, but also the venerable robots that allow our page content to be found in the first place. Read more – ‘Enabling Search Engine Safe URLs with Apache and htaccess’.
For the seasoned Flex developer, we’ve been accustomed to using the Flex Component Explorer as a reference. However, this is set to change with a great new application called Tour de Flex.
Tour de Flex is a desktop application, built using AIR, with the goal of providing a way to explore Flex’s capabilities and resources, including the core Flex components, Adobe AIR and data integration. Read more – ‘Tour de Flex Hits the Ground Running’.
A common need in SQL is the ability to iterate over a list as if it were an array. In SQL it is not possible to declare arrays, unlike other programming languages such as ColdFusion, ActionScript and Java. Fortunately, there is a way around this problem: use a User-Defined Functions (UDFs) to create a tabular version of the data. Arrays are, after all, essentially tabular data (at their simplest, one dimension level). Read more – ‘SQL User-Defined Function: ListToTable’.
Last weekend I attended Barcamp Brighton 3.

SQLite is a mostly ACID-compliant relational database management system contained in a relatively small (~500kB) C programming library. The Adobe AIR runtime includes the SQLite embedded database for use by Adobe AIR applications. This allows applications to run and store data locally and or synchronise the datastore with online repositories. Read more – ‘Preventing SQL Injection in an AIR Application’.
In my previous post, What is a SQL Injection Attack, I gave a brief overview of SQL injection and Cross-Site Scripting (XSS), primarily with regard to websites. In the example given, we saw that an attack could take the form of a ‘hacked’ URL which contained either a literal SQL statement, or a hexadecimal string that could be interpreted by an insecure SQL database server. Read more – ‘How to Fix a SQL Injection Attack’.
Over the past few weeks, subversive elements in the international arena have decided that attacking websites is a fun thing to do! The online world has become the new battle ground between nations vying to de-stabilise rivals. This may seem all very Jack Bauer, but we are increasingly seening ‘SQL injection attacks’ eminating from countries such as Russia, China and North Korea. Of course, that doesn’t mean our countries aren’t doing the same in return, but we only see the results from foreign-based attacks. Read more – ‘What is a SQL Injection Attack’.
The Adobe ColdFusion 8 Developer Exam arrived earlier this year and it is about time I took it. But like Ben Nadel, the exam scares me! Why? Because there is so much more to know. With the introduction of new AJAX tags, native JSON support, .NET integration, image manipulation, threading, interfaces, not to mention full PDF integration, the presentation builder and across the board enhancements, there are a lot of new things to know. Read more – ‘A Minor Rant About The ColdFusion 8 Developer Exam’.

With the release of ColdFusion MX 7 came the introduction of the Application.cfc ColdFusion component. This component replaced the traditional Application.cfm and OnRequestEnd.cfm ColdFusion application templates. Furthermore, if Application.cfc is present, both of these templates are ignored by the application.
In addition to replacing the Application.cfm, the Application.cfc introduced a number of built in methods that handle specific events. These events, as discussed in detail below, allow for a greater control over events within the application. Read more – ‘Anatomy of the Application.cfc in ColdFusion 8’.
The Web Standards Project (WaSP) is to expand its scope of collaboration with Adobe to advance web standards. Having successfully completed its initial goals for assisting Adobe's Dreamweaver team in supporting Web standards, the Web Standards Project's Dreamweaver Task Force will be renamed the Adobe Task Force to reflect its widened scope. The Adobe Task Force will collaborate with Adobe on all of the company's products that output code or content to the Web, and will continue to advocate compliance with Web Standards and accessibility guidelines by those who use Adobe's products to design and build Web sites and applications. Read more – ‘Web Standards Project Expands Collaboration with Adobe’.
The THIS scope in the Application.cfc contains several built-in variables that allow you to set the properties of the application; the name, session management etc. With the release ColdFusion 8 comes the introduction of application-based pathing in the form of the THIS.mappings and THIS.customTagPaths variables. Read more – ‘Application-Based Paths in ColdFusion’.

Following a conversation with a friend regarding how ColdFusion handles arrays and structures in 'the background', I was interested to find out what Java classes each were mapped to. This was a relatively simple case of using the functions getClass(), getSuperClass() and getName() to parse out the name of the Java classes. Read more – ‘The Java Behind a ColdFusion Array and Structure’.
Array and Structures are considered to be complex data types in ColdFusion. In contrast, simple data types are ones that contain a single piece of data, such as an Integer, String, or Boolean value. A complex data type can contain multiple pieces of data, which, in the case of arrays, are usually related. All the data are referenced under a single variable name. You can think of a complex variable as a variable that contains a collection of other variables inside it. An array maps Integers to arbitrarily typed objects (Integers, Strings, Booleans and Objects) while a structure, or associative array, maps arbitrarily typed objects to arbitrarily typed objects. Read more – ‘The Inner Workings of a ColdFusion Array and Structure’.
New Atlanta is announcing today, at CFUnited Europe - a ColdFusion Markup Language (CFML) technology conference in London, U.K.- that they will be creating and distributing a free open-source Java Platform, Enterprise Edition (Java EE) version of BlueDragon, their ColdFusion-compatible web application server. Read more – ‘New Atlanta Open-Sources BlueDragon’.
In an earlier post I eluded to the implicit creation of arrays in ColdFusion 8. Well, the same can be said of structures.
A structure, also known as an associative array, is a complex data type composed of a collection of keys and a collection of values, where each key is associated with one value (a key-value pair). The operation of finding the value associated with a key is called a lookup or indexing, and this is the most important operation supported by a structure. The relationship between a key and its value is sometimes called a mapping or binding. For example, if the value associated with the key "Age" is 29 and "City" is "London", we say that our structure maps "Age" to 29 and "City" to "London". Read more – ‘Implicit Structures in ColdFusion 8’.
An array is a data structure consisting of a group of elements that are accessed by indexing. In most programming languages each element has the same data type. However, ColdFusion, as we will see, is not strictly typed and therefore allows any data type to be stored in combination. This allows strings, integers, booleans and other complex data types all to be stored in the same array. However, doing this certainly isn't a good practice as it causes signification complication when accessing the stored data.
Variables of a simple data type commonly only store a single value but, in some situations, it is useful to have a variable that can store a series of related values - using an array. Arrays are described as complex data types because they can hold data in a structured, complex way. Read more – ‘Implicit Arrays in ColdFusion 8’.
In arithmetic and algebra, when a number or expression is both preceded and followed by a binary operation (a calculation involving two operands), a rule is required for which operation should be applied first. From the earliest use of mathematical notation, multiplication took precedence over addition, whichever side of a number it appeared on. Thus 3 + 4 — 5 = 5 — 4 + 3 = 23. Read more – ‘Operator Precedence in ColdFusion’.
GeSHi started out as a module for the phpBB forum system to enable highlighting of programming languages, which was largely unavailable at the time. Since its conception it has spawned into a standalone project, supported by many web-based PHP content management systems. Read more – ‘Generic Syntax Highlighter (GeSHi) for ColdFusion’.
In the following series of posts, I will introduce the changes and show some simple examples. The first in the series is Arithmetic Operators.
Arithmetic operators take numerical values (either literals or variables) as their operands and return a single numerical value. The standard arithmetic operators are addition (+), subtraction (-), multiplication (*), and division (/).
Ruby is a language of careful balance. Its creator, Yukihiro â€œmatzâ€ Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming. Read more – ‘UK Ruby User Group on LinkedIn’.
Installing PHP is a relatively simple task one would think. Indeed it is simple, but configuring the php.ini isn't; at least not so on Windows Vista! It is infuriating when such a relatively simple task is made inordinately complicated because of the nuances of Vista permissions. What started out as a 5 minute task took a significant number of hours searching for a suitable answer on Google, and not only by myself. Read more – ‘PHP.ini Permission Problems on Windows Vista’.
Installing PHP with Apache on Windows Vista is a relatively simple task until you try an configure the settings in php.ini. Problems can occur and stem from the fact that when you install PHP and edit the php.ini file, you need to not only be logged in as Administrator, but run the installer and Notepad text editor as Administrator. The php.ini file also needs to be located in the Windows directory. Read more – ‘Configuring PHP with Apache on Windows Vista’.
Microsoft is finally making real efforts to woo the designer community who have traditionally worshipped the Adobe and Mac product ranges. One new product that addresses this previously overlooked community is Silverlight, which uses the XAML technology and is touted as Microsoft’s Flash killer. For anyone who is keen to listen, Microsoft proposes that Silverlight will achieve similar results to Flash, but it does so in an entirely different way and has different aims. So, the big question is, will Microsoft be able to break the dominance of Adobe’s Flash platform, that is available on the PC, Mac and mobile devices alike? I’m sure the jury is out on that one, but it can be said it is an uphill task. Read more – ‘Web 2.0 and Beyond with Silverlight and XAML’.
After installing ColdFusion 8 and Apache successfully you may still see an "HTTP 500 Internal Server Error" when navigating to a ColdFusion page. All is not lost, you simply need to configure, or check the configuration of Apache. Apache requires very little post installation modification, but it is always good practice to check the httpd.conf file to ensure that the ColdFusion "install" scripts did what they were supposed to do. Read more – ‘Configuring ColdFusion 8 with Apache’.
A few months ago I posted an article on Installing Apache on Vista, and it proved to be extremely popular. It appears that I was not the only one who found it a non trivial matter.
Now it is the turn of ColdFusion 8. ColdFusion 8 as we well know is the latest and greatest incarnation of the ColdFusion platform from Adobe. It has a lot of great new features such as cfimage, cfzip, cfexchange, some contentious features such as cfthread and cfinterface, and some not-so-necessarily-cool new â€œWeb 2.0â€³ features such as cffeed and cfajax. Read more – ‘Installing ColdFusion 8 on Vista’.
Both Web 2.0 and Software-as-a-Service (SaaS) almost always depend up on the browser as a common denominator. It is with the web browser that web-based applications are accessed and run, yet the browser model is rapidly reaching its limitations. Prism is part of an experiment by Mozilla designed to bridge the divide in the user experience between web applications and desktop applications. Read more – ‘Refactoring the Web with Mozilla Prism’.
Companies need to make the most of Web 2.0, and web content management tools can help firms meet user demand for interactive websites. These tools aren't simply restricted to the standard content management systems (CMS) used to publish text to a website, but tools that include file sharing, information sharing and instant messenging among others. Read more – ‘Tools to meet the Web 2.0 challenge’.
ColdFusion has never satisfactorily removed whitespace from generated content, however, removing this whitespace can dramatically improve your website's performance. Take a 100KB page for example. If 20% of the page is made up of whitespace, that is 20% that is unneccessary and 20% bandwidth cost that can be saved. Read more – ‘Eliminating Whitespace in ColdFusion’.
Killing ColdFusion is something I love to do!! This time I managed to kill ColdFusion by amending the Class Paths listed in the Java and JVM settings of my local instance of ColdFusion MX 7. When you amend any Java and JVM settings you need to restart the ColdFusion service and hope. Read more – ‘Repairing a Corrupt ColdFusion JVM Config’.

I recently taught a Fast Track to ColdFusion 7 course and what struck me was the liberal use of the isDefined() function throughout the course material. Now, I confess, I have used the function many times in the past, but now more commonly use the structKeyExists() function. So why does Macromedia and now Adobe, still highlight the isDefined() function when, in my opinion, structKeyExists() is more efficient? Read more – ‘isDefined() vs structKeyExists()’.
Apache is controlled by a series of configuration files but the one we will be dealing with here is httpd.conf. This file contains instructions on how Apache should run. Several companies offer GUI-based Apache front-ends, but it's easier to edit the configuration files by hand. Read more – ‘Configuring Your First Local Apache Website’.
I'm a ColdFusion freelance developer and as can often happen, I end up using a spare machine sitting in the corner of a room. Being relegated to the "dunce's corner" is bad enough, but commonly the ColdFusion password has also been forgotten. This happened to me just the other day. So, how do we go about resetting the password? Read more – ‘Resetting a Lost ColdFusion Password’.
Many people who have worked on websites know that standard HTML and CSS allows the webpage author to assign any font of their choosing to a text element on a page. However, they also know that there is no guarantee that the element will show the desired font, as the browsing user may not have the same font, or set of fonts, installed on their local system. More often than not, only a set of "common" fonts are installed, for example Arial on the PC and Helvetica on the Mac. This has been a significant issue which has been addressed by two methods: the Fahrner Image Replacement (FIR) method and the Scalable Inman Flash Replacement (sIFR) method. Read more – ‘Rich Accessible Typography – FIR and sIFR’.

I have been developing with Fusebox with ColdFusion for a long time now and recently I moved to version 5 (when I say recently, on closer reflection I started using 5 shortly after it was released in July 2006...wow its been that long!). A common feature that was found to be lacking was the dump and abort features, so useful in debugging applications. Read more – ‘Fusebox 5 Custom Dump and Abort Verbs’.
Thousands of businesses worldwide face the challenge of establishing their web presence; a goal difficult to achieve without efficient web site development and testing tools. If someone where to ask you how good your website was, how would you answer; could you answer? There are so many factors to take into consideration, such as code validation, speed of download accessibility, usability etc, that there is no one correct answer and subsequently no one website that can provide you the definitive answer.

There is a web browser that has only a vague association with modern web standards. That browser is Internet Explorer 6. Wouldn't it be great if it supported stuff like translucent PNGs? Well, now you can add decent PNG support to IE5.5+ on Windows with no changes to your website HTML source code. This script will add near-native PNG support with full alpha opacity, with only one line in your CSS file, that applies to all <img> tags and also background images! Read more – ‘PNG Support in IE6’.
Almost every web application will benefit from the compression of content. A compression filter optimises the size of the content that is sent from a webserver to a web browser via the Internet. Since generating content and serving pages via the World Wide Web is the core behind web applications, it is simple components that aid these processes that are incredibly useful. This is where servlet filters come into play. Read more – ‘Poor Man's HTTP Compression with ColdFusion’.

A new breed of Web-based data integration applications is emerging across the Internet. Colloquially known as mashups, their popularity stems from the emphasis on interactive user participation and the manner in which they aggregate third-party data. A mashup is a website or web application that seamlessly combines content from more than one source into an integrated experience. Mashups are an exciting genre of interactive Web applications that are characterised by, and draw upon, content and functionality retrieved from external data sources to create entirely new and innovative services. They are a hallmark of the second generation of Web applications widely known as Web 2.0. Read more – ‘Wise Up to Mashups’.
By itself, Firefox is a lean and fast browser, but lacks many functions useful to a Web Developer. This is where extensions come to the rescue.

All of these plugins are great for developing and bug testing web sites within the Firefox browser environment. Read more – ‘Firefox Extensions for Web Developers’.
Object-Relational Mapping (or ORM), is a programming technique that links databases to object-oriented language concepts, creating (in effect) a "virtual object database". There are both free and commercial packages available that perform object-relational mapping, although some programmers opt to code their own object-relational mapping for their systems. Read more – ‘ColdFusion ORM Frameworks & Tools’.
A CAPTCHA (an acronym for "completely automated public Turing test to tell computers and humans apart", trademarked by Carnegie Mellon University) is a type of challenge-response test used in computing to determine whether or not the user is human. The term was coined in 2000 by Luis von Ahn, Manuel Blum, and Nicholas J. Hopper of Carnegie Mellon University, and John Langford of IBM. A common type of captcha requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen. Because the test is administered by a computer, in contrast to the standard Turing test that is administered by a human, a captcha is sometimes described as a reverse Turing test. This term, however, is misleading because it could also mean a Turing test in which the participants are both attempting to prove they are the computer. Read more – ‘CAPTCHA’.
One of the many reasons to use ColdFusion MX is that it has a large, standard toolset that enbales the creation of full-featured, dynamic Web applications. The tag-based language makes it relatively simple to query a relational database and send e-mail. In a similar way, you can create and search Verity full-text indexes. Read more – ‘ColdFusion & Lucene’.
For many ColdFusion developers, server setup, tuning, troubleshooting and configuration is one of the least understood areas of ColdFusion. Achieving the highest possible performance and scalability with a ColdFusion MX application is a complex combination of many different factors. Standard performance tuning guidelines in conjunction with the tips provided below should allow you to achieve maximum application performance and scalability. Performance refers to the response time of requests to CFML pages and Components (CFCs), whilst scalability refers to how the performance results change when the load on the server increases. Read more – ‘Coldfusion MX Tuning’.
CFML is the name of the scripting language used by ColdFusion and several alternative server environments. It stands for ColdFusion Markup Language and is similar to HTML in appearance in that it uses tags. CFML is the code that powers ColdFusion, a program available from Adobe (formerly Macromedia), as well as such engines as BlueDragon, IgniteFusion, Railo, Coral Web Builder, and other web development platforms. Read more – ‘ColdFusion (CFML) Engines’.
Bryan Kaiser & Michael Haynie talk about the usual news and then digress into the topic of the future of ColdFusion and its limited uptake in the developer community. This is a hot topic with a number of key figures in the ColdFusion community, in particular Simon Horwith and Ben Forta, writing articles to 'defend' ColdFusion, something I find myself doing almost on a daily basis. Read more – ‘The Coldfusion Podcast Episode 19 – Where is Coldfusion?’.
With the introduction of ColdFusion MX, the ColdFusion community is maturing. Most CF developers have moved beyond spaghetti code and the mixing of business logic with presentation code. But it can be difficult and wasteful to "re-invent the wheel" for every application you write. Frameworks can help promote good development practices, standards, and a sound foundation for creating an application. Read more – ‘ColdFusion Frameworks’.
