I'm not sure that everyone else is following what you're talking about but it may be me so apologies if so. You can access the query string with `$cgi_object->self_url()`, `split` it on the forward-slash into an array, `shift` off the sections and get your script to respond based on what they contain. An example of this procedure can be found in the source of Maypole (look at the `parse_path()` method. If, for whatever reason, you just want to set up a simple web app that works this way to see how you get on, you might find CGI::Application::Dispatch useful; it loads CGI::Application modules and runs their so-called `run-modes' according to the path in the query string.

Didn't understand quite well your idea. But, you have at $ENV{PATH_INFO} the path not processed by Apache. So, if you have the CGI at `/foo`, when you call `/foo/bar` the value of that hash position have `/bar`. Update: Thanks great merlyn for correcting me the key name. Alberto Simões	[reply]

I think you mean PATH_INFO (yeah, bad name for it), not EXTRA_PATH. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

I don't know how it's done in other server/OS configurations, but with Apache/Unix, the CGI script can inspect the environment variable `DOCUMENT_ROOT` to get a physical path. From there one can get a physical path to `/path/to/stuff` as `/path/to/docroot/path/to/stuff`. the lowliest monk	[reply] [d/l] [select]
