I want to rewrite URLs from this: http://www.mydomain.com/identifier/path/page.aspx?param=value To this: http://www.mydomain.com/path/page.aspx?id=identifier¶m=value The problem is, the "identifier" part needs to be matched against a database table, so it could be anything (ie I can't match it with a regex). I thought about adding a "go" pseudo-folder in front of the identifier, eg: http://www.mydomain.com/go/identifier/path/page.aspx?param=value Which would let me match the "/go/" - but I'd rather avoid this if possible. Is there a way? Mike
