Hello, I was running a squid proxy for 500 users in single machine itself.Now I have to increase the number of users to 2000 .For that I came to know that,it will be better to provide caching in two machines. For that I have choosen two P1V machines with 2GB RAM each and two 20GB SCSI hardisk for two machines. But please let me know is there any suitable documentation for doing caching in two servers. I have searched but unable to find a good one. Thanks for any help Regards Sridhar ___________________________________________________________ To help you stay safe and secure online, we've developed the all new Yahoo!
