The "Trick" in apache is this: Put a perl script in the main directory with a name like "graph" Then in the apache conf do: <Location /graph> SetHandler cgi-script </Location> (You may also have to set "Options ExecCGI" on either the location or the directory it is in) In your perl script, using "use CGI;" of course you can get the path from your $cgi variable like this: use CGI qw(:standard); my $cgi = new CGI; my $path = $cgi->path_info(); If you went to the site "http://x.org/graph/blue/green/fun.gif" then $path would be set to "/blue/green/fun.gif" Now you can split on / and get your args. If you are getting you data from a DB and want cache's out in the world to cache data that rarely changes, send the proper "Expires: ..." header or the "Last-Modified: ..." header. Building your code inline like this and adding the extra headers all you need to do for the caches. I built a cache in front of a site like this and it saved me about 60% of the load on my processor.
