ColdFusion - how to set Content-Length header
Has anyone successfully added a Content-Length header to regular ColdFusion (I'm using CF9) pages? I'm setting up a new server behind a Cisco load balancer with compression - the box refuses to compress anything without this header, but CF doesn't pass it by default.
<cfheader name="Content-Length" value="something">
will set the header, but finding the right value is a problem.
Any pointers would开发者_开发百科 be much appreciated.
I believe I've solved it:
<cfheader name="Content-Length" value="#getPageContext().getCFOutput().getBuffer().size()#">
I stuck that in onRequestEnd()
and the Cisco box is happily compressing away.
Thanks for the input folks.
I don't love this idea, but could you make some sort of wrapper with cfsavecontent and take the length of that?
Something like:
<cfsetting enablecfoutputonly="yes">
<cfsavecontent variable="testVar">
<cfinclude template="myPage.cfm">
</cfsavecontent>
<cfheader name="Content-Length" value="#len(testVar)#">
<cfoutput>#testVar#</cfoutput>
I'm not sure if the count would be off due to white space issues.
