One more finding, When caching is enabled for static files, following is the behavior of the apache server : -
*For the first request to resource, * Apache server responds with HTTP status code 200 Log message 127.0.0.1 - - [15/Sep/2010:14:17:33 +0530] "GET /test.html HTTP/1.1" 200 367 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.9) Gecko/20100825 Ubuntu/10.04 (lucid) Firefox/3.6.9 GTB7.1" For all other subsequent request Apache server responds with HTTP status code 304 Log Message 127.0.0.1 - - [15/Sep/2010:14:17:38 +0530] "GET /test.html HTTP/1.1" 304 209 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.9) Gecko/20100825 Ubuntu/10.04 (lucid) Firefox/3.6.9 GTB7.1" That look like okay for me as with status code 304, there is no any payload in the http response, but again, what is the need for this server round-trip, when a resource is cached for the 1 year, it should not be asked for again till the time it is not expired. Is this right? Regards, Vijay Shanker Dubey On Wed, Sep 15, 2010 at 1:11 PM, Vijay Shanker Dubey <[email protected]>wrote: > > > I am trying to enable cache on my apahce web server.
