Why so many 304 resposne for MSIE ? I am serving a static JS file, with Squid as reverse proxy to my Apache 1.x, which has the following response to the client: ================= Status=OK - 200 Last-Modified=Thu, 11 Oct 2007 05:04:34 GMT Accept-Ranges=bytes Content-Length=27157 Content-Type=application/x-javascript Date=Tue, 20 Jan 2009 02:36:50 GMT Expires=Fri, 30 Jan 2009 02:36:50 GMT Cache-Control=max-age=864000 Age=14 X-Cache=HIT from webcache-1.example.com Connection=keep-alive ================= You see expire is set to 10 years from now, so I will expect only a very little of 304 (only user press F5 to reload) However, by tracing the squid log, I found The number of reqs of 200 vs 304 on IE: 17785 (200) 12465 (304) The number of reqs of 200 vs 304 on FF: 6507 (200) 333 (304) You see? Why so many 304 resposne for MSIE ? Any idea? Thanks.
