Hi, I am using squid2.6.STABLE6-3.el5 on RHEL5.0, want to update with squid-3.0.STABLE9. could you guide me how to do that. 1. Shoudl i remove squid2.6 first and then install squid3.0. ? 2. Or should install squid3.0 w/o remove squid2.6. ? 3. Can i have both? 4. Is there any other best alternate. squid2.6 is working fince but facing problem to connecting FTP sites on IE7 and authentication with Active Directory. Thanks, Vikas
