Remove a var from URL

[beefo]

Hey'all, I'm looking for a little hint that would be usefull for me. I
sometimes use the technique to add a URL var to include a file, for example a
link that goes to index.cfm?inc=page.cfm redirect to index.cfm which includes
page.cfm... the problem is that I would like to hide this var because if the
user refresh the page, it does the process again and i don't want the page.cfm
to be included again (for example because it does an insert in the
database).... so the cool thing would be to hide inc=page.cfm from the URL so
it would work perfectly ! Is it possible ? Is it possible without making a
redirection...for example Replace(CGI.QUERY_STRING...) and cflocation ? thanks
in advance for your help ! antoine from belgium

Stupid me !!! I have found the answer....perhaps it s not the best way, but it
does work !!


Replace(Replace(CGI.QUERY_STRING,'lang=#Iif(isdefi ned('url.lang'),DE(url.lang),D
E(''))#',''),'&&','&','ALL')

For this example, the VAR i wanted to retrieve is url.lang

Sorry, it seems that it was still bugging when the var was undefined.... so
here is the longest but safest way to do it:


<cfif isdefined('url.lang')>
<cfset newquerystring =
Replace(Replace(CGI.QUERY_STRING,'lang=#Iif(isdefi ned('url.lang'),DE(url.lang),D
E(''))#',''),'&&','&','ALL')>
<cfelse>
<cfset newquerystring = CGI.QUERY_STRING>
</cfif>

<cfoutput>#newquerystring#</cfoutput>
