HistoryColdFusion
MX 7: Added this function.
Function syntaxGetContextRoot()
UsageThis 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.
ExampleThe
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>
