Need to get spidered: should i change dynamic urls to static?

[SulkyGirl]

Have no idea if this is in the right forum: please move it if it's not. :-)

Google is only indexing my front page (index.php). I think it might be because I have dynamic URLS with session IDs? I'm a complete dunce when it comes to programming and all that, so as much as you can dumb-down a response, it would be greatly appreciated. :-)

Some background:

When I FIRST navigate to my site and click on any link, it sends me to a page like this:

[widget.net...]

After that, if I don't delete my cookies, link urls look like this:

[widget.net...]

I just want to get spidered by google. Any and all help would be appreciated. I can alter my .htaccess file, and I ran a test to verify that I could use mod_rewrite or apache or whatever. Help!

in htaccess file:

RewriteEngine On
Options +FollowSymlinks
RewriteBase /

RewriteRule (.*)_(.*).html $1index.php?prod=$2&cat=$3

This would do the following...
someone goes to your url

[widget.net...]
and the following will load up:
[widget.net...]

Is this similar to what your after?

[SulkyGirl]

Similar, but maybe I think the reverse of what I'm looking for? I've gleaned from various websites that Google is only indexing my front page because of the session IDs in my URLs, and possibly also because of the "?" in the URL. So I'm trying to rewrite them WITHOUT the session ID, and if possible, without the "?"

So for being so vague, I know what I want to accomplish, but I barely know what the problem is...

In the meantime you can make a few static landing pages and link from your home page to them. This will increase your site's size, if only be a small amount.

The "?" is not stopping the bots...I have found the session ID is a problem.
