(ATS 4.1.1, Ubuntu Precise 64-bit, reverse proxy) I wanted to test microcaching and I noticed that I can't seem to get ATS to revalidate under 3600 seconds. Tried with 4.0.2 too with similar results.
Anything I can think of for relevant configs (seems like pasting an entire records.config would be too big, though I'll be happy to): CONFIG proxy.config.http.cache.when_to_revalidate INT 0 CONFIG proxy.config.http.cache.heuristic_min_lifetime INT 1 # The only setting I could find that was set to 3600, so I tried changing it Here's an ATS reply for a page that I've got set up with an Expires of 10 seconds: < HTTP/1.1 200 OK < Date: Sun, 01 Dec 2013 15:45:34 GMT < Content-Type: text/html < Content-Length: 3 < Connection: keep-alive < Server: Apache/2 < Last-Modified: Sun, 01 Dec 2013 06:59:50 GMT < ETag: "3-4ec739c172273" < Accept-Ranges: bytes < Cache-Control: max-age=10 < Expires: Sun, 01 Dec 2013 15:44:21 GMT < Age: 83 < Warning: 113 ApacheTrafficServer/4.0.2 A few minutes later it's up to Age: 282. I've got a packet capture to the origin going and at no time did it attempt to revalidate. I clearly have something misconfigured. I also noticed that error pages are also being cached at 3600 seconds (let it run in a loop overnight and it was 3600 seconds every time), despite: CONFIG proxy.config.http.negative_caching_enabled INT 1 CONFIG proxy.config.http.negative_caching_lifetime INT 60 Anybody want to take a stab at what I'm messing up?
