Passing Referer AS ColdFusion CFHttp CGI Value vs HEADER Value?

<!---
	Perform an HTTP GET to grab the target image
	as binary. CAUTION: Once we go beyond the
	vailable year/months (ex. 2007/12), this will
	come back with 200 status, but NOT be a valid
	image binary.
--->
<cfhttp
	method="get"
	url="#strBaseURL#photos/#strName#.jpg"
	useragent="#CGI.http_user_agent#"
	getasbinary="yes"
	result="objGET">
 
	<!---
		Set referrer to be the page that it was called
		from. We want to fake the target server into
		thinking we just came from an internally hosted
		page. Use the HEADER value rather than the CGI
		value.
	--->
	<cfhttpparam
		type="HEADER"
		name="referer"
		value="#strBaseURL#playboy#strName#.html"
		/>
 
</cfhttp>
