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.
