I have stumped myself on this one. This should be easy but...

I am looping through the URL Parameters like this:

<cfloop index=3D"u" list=3D"#cgi.QUERY_STRING#" delimiters=3D"&">
<cfset urlvars =3D listappend(urlvars,"#u#")>
</cfloop>

Then I rebuild the url parameters like this:

<cfloop index=3D"urlparams" list=3D"#urlvars#">
<cfset urlparam =3D listappend(urlparam,urlparams,"&")>
</cfloop>

What I need to do is strip out a variable name IF it exists, namely the =
page variable.=20
All I need to really know is how to skip appending it in my 2nd list =
loop above if the word page is in there.
