Adobe ColdFusion is a commercial rapid web-application development computing platform created by J. Allaire in By version 2 , it became a full platform that included an IDE in addition to a full scripting language.
Allaire and Jeremy Allaire. In Allaire was acquired by Macromedia , which in turn was acquired by Adobe Systems Inc in It is especially well-suited as the server-side technology to the client-side ajax. Other implementations of CFML offer similar or enhanced functionality, such as running in a. NET environment or image manipulation. The engine was written in C and featured, among other things, a built-in scripting language CFScript , plugin modules written in Java, and a syntax very similar to HTML.
In addition to ColdFusion, CFStudio also supports syntax in other languages popular for backend programming, such as Perl. In addition to making backend functionality easily available to the non-programmer, version 4. All versions of ColdFusion prior to 6. This meant that ColdFusion was largely limited to running on Microsoft Windows , although Allaire did successfully port ColdFusion to Sun Solaris starting with version 3. The Allaire company was sold to Macromedia , then Macromedia was sold to Adobe.
Earlier versions were not as robust as the versions available from version 4. With the release of ColdFusion MX 6. Version 6. Version 3. Released in Nov , version 4 is when the name was changed from "Cold Fusion" to "ColdFusion" - possibly to distinguish it from Cold fusion theory. Version 4. IT also added the getmetricdata function to access performance information , additional performance information in page debugging output, enhanced string conversion functions, and optional whitespace removal.
Version 5 was released in June , adding enhanced query support, new reporting and charting features, user-defined functions, and improved admin tools. It was the last to be legacy coded for a specific platform, and the first release from Macromedia after their acquisition of Allaire Corporation , which had been announced January 16, This made portability easier and provided a layer of security on the server, because it ran inside a Java Runtime Environment.
In June Macromedia released the version 6. With the release of ColdFusion 7. The enterprise edition also added Gateways. XML support was boosted in this version to include native schema checking.
ColdFusion MX 7. More than 14, developers worldwide were active in the beta process - many more testers than the 5, Adobe Systems originally expected. In addition, the ColdFusion Administrator for the Enterprise version ships with built-in server monitoring. ColdFusion 9 Codenamed: Centaur was released on October 5, New features for CF9 include:. ColdFusion 10 Codenamed: Zeus was released on May 15, New or improved features available in all editions Standard, Enterprise, and Developer include but are not limited to :.
Additional new or improved features in ColdFusion Enterprise or Developer editions include but are not limited to :. The lists above were obtained from the Adobe web site pages describing "new features", as listed first in the links in the following list. CF10 was originally referred to by the codename Zeus, after first being confirmed as coming by Adobe at Adobe MAX , and during much of its prerelease period. For much of , ColdFusion Product Manager Adam Lehman toured the US setting up countless meetings with customers, developers, and user groups to formulate a master blueprint for the next feature set.
In September , he presented the plans to Adobe where they were given full support and approval by upper management. New or improved features available in all editions Standard, Enterprise, and Developer include:. ColdFusion 11 also removed many features previously identified simply as "deprecated" or no longer supported in earlier releases. For example, the CFLOG tag long offered date and time attributes which were deprecated and redundant, as the date and time is always logged.
As of July , Adobe had released 10 updates [12] for ColdFusion New or improved features available in all editions Standard, Enterprise, and Developer include: [13]. Adobe ColdFusion Release was released on Nov 11th, ColdFusion was code named Project Stratus during pre-release. In Sep , Adobe announced the roadmap anticipating releases in and As for the release, the features anticipated at that time in were configurability modularity of CF application services, revamped scripting and object-oriented support, and further enhancements to the API Manager.
The generated document can then either be saved to disk or sent to the client's browser. ColdFusion was originally not an object-oriented programming language like PHP versions 3 and below. ColdFusion falls into the category of OO languages that do not support multiple inheritance along with Java, Smalltalk, etc.
Each component may contain any number of properties and methods. One component may also extend another Inheritance. Components only support single inheritance.
Object handling feature set and performance enhancing has occurred with subsequent releases. With the release of ColdFusion 8, Java-style interfaces are supported. ColdFusion components use the file extension cfc to differentiate them from ColdFusion templates. Component methods may be made available as web services with no additional coding and configuration. All that is required is for a method's access to be declared 'remote'. Consider the GET request as shown.
This will invoke the component's search function, passing "your query" and "strict" as arguments. This type of invocation is well-suited for Ajax -enabled applications. The ColdFusion server will automatically generate documentation for a component if you navigate to its URL and insert the appropriate code within the component's declarations. This is an application of component introspection, available to developers of ColdFusion components.
Access to a component's documentation requires a password. ColdFusion provides several ways to implement custom markup language tags, i. These are especially useful for providing a familiar interface for web designers and content authors familiar with HTML but not imperative programming.
The traditional and most common way is using CFML. For example, the file IMAP. ColdFusion can also be deployed to servlet containers such as Apache Tomcat and Mortbay Jetty , but because these platforms do not officially support ColdFusion, they leave many of its features inaccessible.
Prior to ColdFusion 7. NET by declaring them as web services. However, beginning in ColdFusion MX 7. Recently, there has been much interest in Java development using alternate languages such as Jython , Groovy and JRuby. ColdFusion was one of the first scripting platforms to allow this style of Java development. ColdFusion 8 natively supports. ColdFusion developers can simply call any.
NET assembly without needing to recompile or alter the assemblies in any way. Data types are automatically translated between ColdFusion and. NET example:. NET Assemblies remotely through proxy without the use of. NET Remoting. This allows ColdFusion users to leverage. NET without having to be installed on a Windows operating system. When ColdFusion templates are saved to disk, they are traditionally given the extension.
ColdFusion originated as proprietary technology based on Web technology industry standards. However, it is becoming a less closed technology through the availability of competing products.
Such alternative products include :. NET, simply because ColdFusion will run on top of a. NET application server. In March , a known issue affecting ColdFusion 8, 9 and 10 left the National Vulnerability Database open to attack. In April , a ColdFusion vulnerability was blamed by Linode for an intrusion into the Linode Manager control panel website.
In May , Adobe identified another critical vulnerability, reportedly already being exploited in the wild, which targets all recent versions of ColdFusion on any servers where the web-based administrator and API have not been locked down. The vulnerability allows unauthorized users to upload malicious scripts and potentially gain full control over the server.
In April , Adobe fixed a cross-site scripting XSS vulnerability [24] in Adobe ColdFusion 10 before Update 16, and in ColdFusion 11 before Update 5, that allowed remote attackers to inject arbitrary web script or HTML; [25] however, it's exploitable only by users who have authenticated through the administration panel. In September , Adobe fixed two command injection vulnerabilities CVE that enabled arbitrary code and an alleyway traversal CVE From Wikipedia, the free encyclopedia.
