Hi Kevin,
I'm not working with FreeTrade. At the moment I'm using it as an
example of good style and organization.
But I was involved with addressing this issue a while back.
Some resources -
Jeremy Brand, http://www.jeremybrand.com
has a snippit of code doing it one way.
http://www.nirvani.net/software/variables_from_uri/
Tim Perdue, from phpbuilder.com wrote an article on this
'Building Dynamic Pages With Search Engines in Mind'
And some threads in the archives:
Subject: Re: [PHP] search engines ignoring .php3 pages
Subject: Re: [PHP3] Small bug
Andreas Schamberger <[EMAIL PROTECTED]>, http://www.mongokrieger.de
Has a semi-fork of the old Back-End v0.3.3 code, called
back-end_v0.4.2andi, that has implemented some url_handler code.

The url_handler code is in 'main_file'
(more comments below).

As Tim's article will show, you can also use the
<Files scriptname>
Forcetype application/x-http-php
</Files>
directive to execute a script with any name, excluding an extension
that can contain your urlhandler code.

The only way we got around this was basically have copies of a main_urlhandler.php
script named after categories or directories. Of course that's a pain. Used a perl
script to handle
making copies of the main script so that any changes were all done just in the main_
urlhandler script. And you had to have entries of the above <Files...Forcetype ...
in httpd.conf or .htaccess for every category name. But it eventually worked.

Another thing to watch out for, is solutions to this problem involving using
header(location: )
This is implemented as an internal apache redirect which, apparently, many(?) search
engines choke on. I don't know the whole story on this.
It's a good problem to work on.
Good luck,
MD
