	mod_perl is great if you want to make complex decisions to arrive at
the dynamic document in question, but if you just want to provide mappings
based on a simple key/value table, I strongly suggest you use mod_rewrite.
Here's a good starting point for that:

	http://httpd.apache.org/docs/2.2/rewrite/

	The advantage is that in most cases, you end up with 2 or 3 lines of
code inline in your httpd.conf to handle the problem, instead of the
mod_perl way of writing a separate .pm with a handler whose overhead is
going to be at least 10 lines before you even start coding.

	I use both extensively and together; mod_perl for the content,
authentication, etc... and mod_rewrite for traffic control.

	Cheers,
		Tyler
