ColdFusion is a rapid web application development platform which enables you to build large, complex, and dynamic websites. It enables you to create powerful server-side web applications very quickly, with much less code.ColdFusion integrates many Internet technologies such as XML, Java, web services etc.ColdFusion consists of two main elements
Once you've installed ColdFusion server, you can write code using the ColdFusion Markup Language (CFML). ColdFusion also provides an administration interface (the ColdFusion Administrator), which enables you to customize your ColdFusion environment.
The components that make up the ColdFusion environment are
ColdFusion Application Server: The ColdFusion Application Server processes all the CFML code in the templates passed to it by the web server. It then returns the dynamically generated results to the web server, so that the output can be sent to the user’s browser. It integrates with a number of popular web servers via native APIs and is also capable of running in CGI mode.
ColdFusion Studio: It is an Integrated Development Environment (IDE) for the ColdFusion Application Server. It provides developers with a visual environment for developing, testing, debugging, and deploying ColdFusion applications.
Web server: The web server funnels browser requests for CFML templates through the ColdFusion Application Server. The web server is also responsible for passing the output returned by the ColdFusion Application Server back to the browser.
ColdFusion Administrator: ColdFusion application for configuring and administering the ColdFusion Application Server. The ColdFusion Administrator handles everything from registering and setting up data sources to logging and security.
Data sources: ColdFusion is capable of interacting with a number of external data sources, including databases, Verity collections, LDAP directories, POP3 and SMTP mail servers, FTP servers, and other HTTP servers. This allows you to create ColdFusion applications that send and receive email, transfer files with FTP, query directory servers, and request content from other web servers.
Objects: ColdFusion can interact with various external objects, including COM/DCOM objects, CORBA objects, and Java objects. This allows your ColdFusion applications to interact with third-party components as well as back-end systems written in other languages
Extensions: CFML is extensible through custom extensions written in languages, such as C++, Java, and Delphi, and even CFML. By writing an extension, you can include functionality not natively available in the core ColdFusion language.
When the web browser makes a request to a web server for a template with a .cfm extension. The web server receives the request and forwards it to the ColdFusion Application Server. The ColdFusion Application Server parses the CFML template and processes the tags and functions accordingly, interacting with other services, such as data sources or mail servers.
The ColdFusion Application Server combines its dynamic output with the static HTML in the template and passes the whole page back to the web server. The web server passes the dynamically generated content back to the client machine’s web browser.
