[users@httpd] Apache rewrite help - urgent

[Anoop.V]

I am looking for a rewrite issue for my apache server.
We have some urls wrongly cached by google which making big problems in server. 
Following are some example urls

http://www.mysite.com/?section_id=8
http://www.mysite.com/?section_id=7
http://www.mysite.com/?section_id=9
http://www.mysite.com/?page_number=2&section_id=13
As it starts with the '?' and does not have a proper query request part, I am 
facing some problem. Can someone help me to fix this?
Thanks,
