Hi, Fatiha,

You can try calling "GET /path/to/directory/" and parsing the HTML or
XHTML results of that - assuming "directory listings" are enabled.  Most
web servers have that turned off.

Many web servers probably return HTML 3.2, which XML parsers hate, so
good luck!

Assuming that works, you can then follow it up with
"GET /path/to/directory/the_file_I_like" 

But you are depending on your webserver serving directory listings in a
consistent fashion.  Tomcat does directory listings one way, IIS
another, and Apache has his way.

If you are trying to determine file size or last modified datestamp
through this, I would recommend using
"HEAD /path/to/directory/the_file_I_like" instead.

But if you are trying to discover new files that you didn't know about
before, then this (or webcrawling) is the only option I know of.

Unless you can open up FTP to the same directory?


yours,

Julius
