After another discution, i would like to create two squid server on the same server. I create 2 different tree with different parameters i can run the first, but when i try to load the second, i have the following error displayed: 2006/04/19 16:15:50| Squid is already running! Process ID 1596 I had in squid.conf this line (in each squid.conf file): pid_filename c:/squid_basic/var/logs/squid.pid (with different path for each one) And i have always the same error, reporting that squid is always running... Is there a possibility to deactivate this check on squid start? And (more important) can i execute many proxy on the same computer? ... guillaume ...
