Need to remove session IDs

[popeye]

Hi:

I want to remove session IDs - but only when a bot (user-agent: googlebot, slurp, etc.) is crawling my site (apache + mod_perl).

In my site, session IDs are not generated on the initial page requested (whether index or interior page); but are generated in subsequent links from that requested page.

Example:

page requested:
www*example.com/ (and will appear as such to bots)

links on requested page appear as:
www*example.com/dir1/?sessionID=aa162314bDRa53872123
www*example.com/dir2/?sessionID=aa162314bDRa53872123
www*example.com/dir3/?sessionID=aa162314bDRa53872123
and so on....

Any suggestions, references, or examples of code that has worked for anyone else? I am new at this so simple is better.

Thanks.
