Do SE bots spider pages with internal sessions?

spider sessions php

I was wondering whether search engine bots spider pages that don't have a Session ID in the URL, rather in the php page and forms embedded? Let me elaborate more on this.
I have a php page which starts a new session and I'm using mod-rewrite for URLs, so like www.mydomain.com/english/something.htm will redirect to www.mydomain.com/?file=something.htm and my content is stored in MySQL. So the php file is called everytime and the session is started. I have a submit form on every page on my site at the top and the session code automatically inserts the session ID into it like this '<input type="hidden" name="PHPSESSID" value="d10e1157482bedd8cb68e63f92b6010a" />'. If you go to the site, you cannot view the source of it. So now back to my question, can search engines spider it?
Thanks and appreciate your response!

The search engine don't have a problem with spidering URLs with special characters, such as? or &, but it is my understanding that they will not spider URLs with session IDs.

I have moved this thread to a more appropriate forum so that the right members will provide their knowledge and experience.

They spider ours with sessions. It's a pain b/c the sessions expire and the URL is pretty much useless for the next 30 or so days it comes up in the listings. We are working on programming that recognizes the bots and serves them pages without session IDs.
