 You'll want to "attach" a procedure to a URL space. One of two functions
 will be useful: ns_register_proc or ns_register_filter. Take a look in
 the TCL API docs (eg,
 http://www.aolserver.com/server/docs/2.3/html/tcldev.htm)
 to read about them.

 Basically, from a TCL module (not pages) you'd want to do something
 like:

   ns_register_proc GET /userpages/* servePage

 where servePage is a TCL proc that dynamically creates and sends the
 page.

 When usng ns_register_proc, you *must* create a response for the
 browser.
 If you use ns_register_filter, you have the option of letting AOLserver
 perform its default action for the URL. So with:

   ns_register_filter postauth GET /userpages/*  servePage

 The proc servePage can check a database for existence of userid or some
 such,
 and if it doesn't exist, return a code that tells AOLserver to continue
 processing
 the URL (perhaps another registered filter, or proc, but usually checks
 the filesystem). In that way, you could have a mixture of dynamic pages
 and static pages on disk in the same URL space. If that was desireable
 or needed.

 Have fun,
