Re: [squid-users] How often is my cache cleared ?

Thanks for your answer Robert.

Of course I had already read all the clear explanations given in the squid.conf
file.
It explains that when the garbage interval passes, all user credentials that
have passed their TTL are removed from memory.

This is why I thought that if I set both authenticate_cache_garbage_intervall
and authenticate_ttl to zero, then no authentication should be kept in memory
and I should be prompted for authentication again for each new request. But it
doesn't.

Maybe now you understand better where my resonning is wrong... could you
explain this to me ?

Another thing is that I was looking for the cache ttl in general (not only the
username cache which default ttl value is mentionned in
authenticate_cache_garbage_interval.

Thanks in advance

It determines how often the user cache inside squid is garbage
collected. The comments in squid.conf.default are fairly clear IMO. Have
you read them? (Include the bit that says "Only change if you have good
reason to.")?

Explained in squid.conf.default.

Ditto.

Ditto.

At the garbage collection interval. The default is listed in
squid.conf.default.

They have no impact on how often you are prompted for authentication.
None. Zip. Nada.

That is up to the browser, not squid.
