<cfif cgi.HTTP_REFERER IS NOT "">
cgi variable exists
<cfelse>
cgi variable does not exist
</cfif>
<cfoutput>#CGI.HTTP_REFERER#</cfoutput>
However I am not getting anything back in the cgi variable.
Any comments appreciated.

Just to eliminate any other kind of white space characters, I usually do a trim
on anything I'm trying to compare to an empty string.
<cfif trim(cgi.HTTP_REFERER) EQ "">
I also usually try to phrase this as a binary comparison.
<cfif len(trim(cgi.HTTP_REFERER))>
