We need to reconfigure or restart the Squid server after modifying the Squid configuration file. Now, if we try to browse www.example.com using our proxy server, then we'll notice an output similar to the following, in our cache.log file. Please note that we have removed the timestamp from the following log messages for a clearer view:

httpStart: "GET http://www.example.com/"
