ColdFusion MX 7: Added this function.

GetContextRoot()

The path from the web root to the context root for the current page. The path starts with a forward slash character (/) but does not end with a forward slash character (/). For applications in the default (root) context, returns the empty string.

This function is equivalent to calling GetPageContext().GetRequest().GetContextPath(). On J2EE configurations, it returns the path from the Web root to the J2EE context root of the ColdFusion J2EE application. On server configurations, it returns the empty string, because the context root is at the web root.
This function is useful in applications that might be installed at varying J2EE context roots.

The ColdFusion Administrator uses the following line to get the location of the administrator directory:

<cfset request.thisURL = "#getContextRoot()#/CFIDE/administrator/">

The Administrator uses the returned value in places where it uses a URL to access Administrator resources, such as images, as in the following line:

<a href="index.cfm"><img src="#request.thisURL#images/back.gif" width="16" 
            height="16" border="0" alt=" "></a>
