I am looking to deploy Squid as a reverse proxy and i had couple of questions. We currrently use Bluecoat and Sun Web proxy and i am able to do the following things 1) How would i flush objects from cache?
The whole lot: http://wiki.squid-cache.org/SquidFaq/ClearingTheCache or individually via: HTTP "PURGE" requests HTCP "CLR" requests squidpurge tool commands.
2) Can i flush the entire cache without restarting Squid?
Yes ... but it takes a LONG time to do N objects individually. Restart without a cache to load takes milliseconds.
3) Can i set the configuration to expire objects at a certain time every day regardless of when the object was cache during the previous 24 hours?
Use of the Expiry and Cache-Control mechanisms properly can do just about anything. Correct use will make all proxies not just your reverse one handle the site fine and remove a lot of customer problems.
Objects which arrive with header "Expires: XX" will expire at XX timestamp and be replaced on their next use.
