[squid-users] how to set up expires header in squid?
hi, everyone i have a web server(apache 2.0.x) and a squid(2.6) in front of the web as the reverse proxy. in the web server, i have set up the mod_expires module to export the Expires HTTP header as 1 year. and it works, when i visit the apache directly, here is the http header info -- [shell]# curl -D- -o /dev/null http://www.mydomain.com/test.png HTTP/1.1 200 OK Date: Fri, 09 Apr 2010 07:52:21 GMT Server: Apache/2.0.53 (Unix) mod_perl/1.99_14 Perl/v5.8.5 PHP/5.0.3 mod_ssl/2.0.53 OpenSSL/0.9.7e mod_fastcgi/mod_fastcgi-SNAP-0404142202 Last-Modified: Thu, 06 Apr 2006 12:03:53 GMT Accept-Ranges: bytes Content-Length: 512 Cache-Control: max-age=31536000, public Expires: Sat, 09 Apr 2011 07:52:21 GMT Content-Type: image/png --- and then i put the squid in front of the web, set up the squid as a reverse proxy. then i visit the same URL again, then i got the different header -- [shell]$ curl -D- -o /dev/null http://www.mydomain.com/test.png HTTP/1.0 200 OK Date: Fri, 09 Apr 2010 08:56:00 GMT Server: Apache/2.0.53 (Unix) mod_perl/1.99_14 Perl/v5.8.5 PHP/5.0.3 mod_ssl/2.0.53 OpenSSL/0.9.7e mod_fastcgi/mod_fastcgi-SNAP-0404142202 Last-Modified: Thu, 06 Apr 2006 12:03:53 GMT Accept-Ranges: bytes Content-Length: 512 Content-Type: image/png Age: 1025 X-Cache: HIT from squid.mydomain.com Via: 1.0 squid.mydomain.com:80 (squid/2.6.STABLE23) Connection: close --- the pic loads correctly, but as you can see, the "expires" header is gone (compare with visit apache directly). but i need to keep it. so, i'm wondering how to set up squid to export the "expires" header? i have tried use refresh_pattern, but no luck.. i totaly have no idea now. so i have to look for help here. any tips are appreciated? thank you~~
