I'll just throw this out there as an alternative. I had an app that
accepted a url and to validate it, I actually used CFHTTP to go get the
page and see what I got back (404, etc). I made a little tag to do it
easily. If someone is interested, I can post it...
> <CFSET
> url="http://www.houseoffusion.com/test/test2.cfm?name=michael&date=1";>
> <CFSET
> sUrl=REFindNoCase('^(https?)://([-a-z0-9._]+):?([0-9]*)([-a-z0-9/\._]*)\??([
> -a-z0-9/\&.?=]*)', url,1,1)>
>
> <CFLOOP from="2" to="#ArrayLen(sUrl.pos)#" index="i">
> <cfoutput>#mid(url, sUrl.pos[i], sUrl.len[i])#</cfoutput><BR>
> </CFLOOP>
> <CFOUTPUT>
> </CFOUTPUT>
> returns a structure with the following information
> 1. entire string
> 2. protocol (http/https) - The question mark after the s makes that
> character optional
> 3. domain name (www.houseoffusion.com) - a string of 1 or more characters
> that can be a-z, 0-9, -, _, or .
> 4. port (80) - 0 or more numeric characters
> 5. path (/test/test2.cfm) - 0 or more characters that can be a-z, 0-9, -, _,
