Thank you Henrik. I have one last question concerning stale-while-revalidate, as the docs don't seem to answer it. Say you set stale-while-revalidate to something like 30 minutes. Once validation occurs, does squid continue to serve the stale content for 30 minutes (even though the object has infact been updated), or will all new requests immediately be served the new, updated object? 2010/8/2 Henrik Nordström <henrik@xxxxxxxxxxxxxxxxxxx>: > sön 2010-08-01 klockan 11:52 -0400 skrev david robertson: >> On Sun, Aug 1, 2010 at 1:12 AM, Amos Jeffries <squid3@xxxxxxxxxxxxx> wrote: >> > If stampeeding is a worry the stale-if-error and stale-while-revalidate >> > Cache-Control: options would also be useful (sent from the origin web >> > server).
