Try running Squid with a bogus httpd_accel_host value. For example: httpd_accel_host blah.blah.blah Does it still work, or do you get error messages? -
Disconnect Squid's network connection while your router/switch is diverting traffic to it. Does the network device bypass Squid? How long does it take to notice the problem? -
Repeat the same experiment, but this time kill the Squid process instead of unplugging the network cable. -
Enable Squid's user -agent log and see if you are intercepting any nonbrowser web traffic. |
