From: vikas rawat <rawat.vikas@xxxxxxxxx> > But if i have both 2.6 and 3.0, will they not conflict. How did you install squid 3.x? from source or rpm? To keep both versions, you have to use different directories (install/conf/logs) and init.d scripts. Use ./configure --prefix=$DIR ... to compile squid 3.x and install it in directory $DIR (also see --sysconfdir) Then, copy /etc/init.d/squid and change the directories as needed. JD
