How to add content by url?

[badmonkey]

Anyone know an easy way to include content on a page by a field in the url? I am assuming this probably easy but I cant figure it out.

What I am trying to do is take a url like:
[domain.com...]
and make "widget" display on my page.

Any help?

use one of the vars in your $_SERVER [php.net] array to get the path you are currently at

then split it and test it
