Sessions and search engine spiders

Hello -

In a default rails app, if cookies are turned off, Rails creates a
session file in /tmp for every single request. If my site gets
crawled by googlebot won’t this create thousands of sessions that
don’t need to be created?

I read the wiki regarding session management but there doesn’t seem to
be the middle ground of “don’t create a session unless I tell you to”
such as you have with servlets.

Any ideas on how to accomplish this would be appreciated.

Cheers
Mike
