Hi, I am trying to fully understand the refresh algorithm Squid is using: FRESH if expires < now, else STALE STALE if age > max FRESH if lm-factor < percent, else STALE FRESH if age < min else STALE I disabled the last-modified header on my apache server for an objekt test.html for testing purposes. My refresh_pattern looks like this: refresh_pattern test3 10 10% 300 If I request something like echo -e "GET http://example.com/test.html HTTP/1.0\n\n" | netcat example.com 80 the answer from squid is HTTP/1.0 200 OK Date: Tue, 25 Aug 2009 19:01:46 GMT Server: Apache/2.2.6 (Unix) PHP/5.2.5 ETag: "4d04f6-2-f4490a00" Accept-Ranges: bytes Content-Length: 2 Content-Type: text/html Age: 346 X-Cache: HIT from example.com Via: 1.0 example.com (squid/3.0.STABLE18) Connection: close It is strange to me that Squid always produces a hit. Since the object does not have a last-modified or expires header, the Squid algorithm should look simply like this: STALE if age > max FRESH if age < min else STALE But both: age>max and age < min do not work (no refresh of the object is done via Squid), Squid is still caching the object. It only changes if I set percent to 0%, then I receive a MISS, but percent should not be used (since no last-modified-header), should it? I would appreciate any explanations.
