Hi list,

Does anyone know of a quick and easy way (i.e. not involving a comparison
against a massive list of UAs) of telling whether a visitor is a bot or a
human?

I'm doing a site that uses PHP's session handling, which automatically
appends the session ID to every link on a page if the visitor rejects their
session cookie. The problem is that bots will do this, so the URLs will be
indexed by search engines with the session IDs in them - a bit messy.

There are a lot of sites in this situation:
http://google.com/search?q=allinurl%3A%3FPHPSESSID%3D

Anyone got any ideas?

Cheers
Jon
