<!--- write the contents of the http request to a file.

|
The filename is passed with the qqfile variable --->

<cffile action="write" file="#ExpandPath('.')#/#arguments.qqfile#" output="#arguments.content#">
|
|
|
|
<!--- if you want to return some JSON you can do it here.
|
|
I'm just passing a success message --->
|
|
<cfset local.response['success'] = true>
|
|
<cfset local.response['type'] = 'xhr'>
|
|
|
|
<cfreturn local.response>
|
|
</cffunction>
