It was the first time I used CREATE-REGEX-DISPATCHER and I had to
parse the URL in the handler with the same regex. It was just an
idea.

But I like CL-PPCRE:SCAN-TO-STRINGS more and it's clearer this
way, without the specials.


I've done some projects which used mod_rewrite. Typical rewrite
rules matched and parsed a URL giving the registers as parameters
to the "real" address. Maybe that's the reason for my first
impression using CREATE-REGEX-DISPATCHER.
