Hi, I am trying to understand why certain objects are cached and others not (in a web accelerator setup). For example, squid is caching http://my.site.org/images/hello.gif but not http://my.site.org/js/hello.js Both files are well under any limits (< 2KB) But for another site, pretty much everything is getting cached, i.e., http://my.othersite.org/images/hello.gif and http://my.othersite.org/js/hello.js are giving hits. The only difference I could see in the headers (as reported via the firefox plugin httpheaders) is that the first js is gzipped. Could that be it? I tried disabling the apache gzip exclusion thingie #acl apache rep_header Server ^Apache #broken_vary_encoding allow apache But that didn't seem to change anything. Does anyone have any pointers? Cheers Anton
Here is what httpheaders gives http://www.my.domain.name/js/general.js GET /js/general.js HTTP/1.1 Host: www.my.domain.name User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: Wysistat=0.9275272298400944_1179412290656%A72%A71179412348937%A72%A71179398121%A70.9578866789309586_1179398121265; PHPSESSID=27ed1a75d667f05cc961ff76df8bee61 HTTP/1.x 200 OK Date: Thu, 17 May 2007 15:31:02 GMT Server: Apache/2.0.54 (Debian GNU/Linux) mod_python/3.1.3 Python/2.3.5 PHP/5.0.5-1 mod_perl/1.999.21 Perl/v5.8.7 X-Powered-By: PHP/5.0.5-1 Set-Cookie: PHPSESSID=27ed1a75d667f05cc961ff76df8bee61; path=/ Expires: Sat, 19 May 2007 17:31:02 GMT Cache-Control: private Pragma: cache Last-Modified: 28/04/2006 17:22 Accept-Ranges: bytes Content-Encoding: gzip Vary: Accept-Encoding Etag: "dd4dd40f580d39ccada206547449762b-1378461273" Content-Length: 796 Content-Type: text/javascript X-Cache: MISS from sub.my.domain.name X-Cache-Lookup: MISS from sub.my.domain.name:80 Via: 1.0 sub.my.domain.name:80 (squid/2.6.STABLE5) Connection: keep-alive X-Antivirus: avast! 4 X-Antivirus-Status: Clean ---------------------------------------------------------- ...
