Re: CF10 and IIS 7.5 - cfheader in 404 custom error handler not working correctly

That didn't solve it for me. Turning on detailed error pages for a 404 error (that is not a CF file) will cause an IIS detailed error page to show.

My workaround is this (404.cfm)

<cfsetting enableCFoutputOnly="true">

<cfheader statuscode="404" statustext="Not Found">

<cfheader name="Connection" value="Close">

<cfsavecontent variable="errorPage">

<cfoutput>

<p>Put your error page in here</p>

</cfoutput>

</cfsavecontent>

<cfcontent reset="Yes" type="text/html">

<cfheader name="Content-Length" value="#Len(errorPage)#">

<cfoutput>#errorPage#</cfoutput>
