It does not matter. Those tricks have such a small impact that it is best to spend you time with known factors. I rank all over the place and I use a dynameic system that just puts /?pane2=blah_blah-blah_blah after the domain.com.

I use 'page-name.htm' for static pages & 'page-name.asp'/php for dynamic pages.

According to the W3C as a professional standards body, my opinion as a user and my experience as writer I have to recommend:

site.com/page-name

Stay away from .cgi and .pl. The Googlebot isn't very good at crawling thoses. If you do those, use mod_rewrite, then you'll get Googlebombed. Also stay away from session IDs.
