Clear Cache

Resetting the cache in squid can often clear up issues without performing a more complicated procedure. Before performing a full reset, try clearing and resetting the cache:

mv /var/squid/cache /var/squid/cache.old squid -z rm -rf /var/squid/cache.old

The old cache should be moved, then reset, and then the old cache should be removed, as above, because removing the cache directory can be time consuming, and if it is moved first, then its removal will not prevent squid from being run while it is happening.
