coldfusion - How to strip out a url variable

Question

I have a url.LoginID, and I'd like to remove it from the address bar when the user clicks on the link to login. It has to be a bookmark, it can't be a form submit.

Q: How do I remove ?LoginID from Index.cfm?LoginID=XYZ&AssignmentID=123

It's probably something along the lines of:

<cflocation url="#cgi.SCRIPT_NAME#?#cgi.QUERY_STRING#" addtoken="no">

Answer 1

Looks like you are on the right track.

If loginID is the only thing in the query string, you can simply cflocation to the destination page without the query string.

If there is other data in the query string, then you can do something like this:

<cfset q = reReplaceNoCase(cgi.query_string, "LOGINID=[^&]+&?", "")>
<cflocation url="#cgi.SCRIPT_NAME#?#q#">

This essentially removes loginid and everything until either the en of the string or the next URL variable.
