I did something like this relatively recently, with the added requirement that
both the variable name and the value be encrypted (fun, eh). On top of that,
there was a handler page that I had to ensure was continuing to attach all of
my url vars to the url for cflocation. I'll give you my code snippets here and
hopefully you can mine something useful out of them:
Handler page looping through variables to attach url scope to cflocation url:
<cfset myhomepage = "this is my link">
<cfset urlscope = "" />
<cfloop collection="#url#" item="key">
<cfif decrypt(key,application.EncryptSeed,"CFMX_COMPAT", 'Hex') EQ
"linkfrom"><!--- var lets me know it's coming from an email; reroute --->
<cfset myhomepage = "different page here">
</cfif>
</cfloop>
<!--- append any url variables --->
<cfloop collection="#url#" item="key">
<cfset urlscope = urlscope & "&#key#=#url[key]#" />
</cfloop>
<cfif len(urlscope)>
<!--- then swap out the first & for a ? and append to our link --->
<cfset urlscope = REReplace(urlscope, "&", "?") />
<cfset myhomepage = myhomepage & urlscope />
</cfif>
<cflocation addtoken="no" url="#myhomepage#">
Then on a given page where I needed to know if an ID had been passed in....
<cfloop collection="#url#" item="key">
<cfif decrypt(key,application.EncryptSeed,"CFMX_COMPAT", 'Hex')
EQ "project_id">
<cfset request.project_id =
decrypt(url[key],application.EncryptSeed,"CFMX_COMPAT", 'Hex') />
</cfif>
</cfloop>
