ColdFusion Components (CFCs) are objects in the environment.

A component method is invoked in the following ways:

  • In the <cfinvoke> tag (Transient objects)

  • In the <cfobject> tag

  • In a URL that calls a CFC file and passes a method name as a URL parameter

  • By using createobject() in <cfscript> or in <cfset>

  • via web services

  • From code

Unlike normal ColdFusion files, CFCs have a .cfc extension.
