i have a php/mysql site and ive managed to use httaccess to hide the query string etc.

i then had a problem with the sessions. so ive managed to disable sessions for google. Now i need to disable them for yahoo, etc .. ive seen lists og bots etc. do i just the ip address for them..

sure you can do it by ip or user agent.
