Re: Problem with mode_expires module

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?

I am trying to enable cache on my apahce web server. I am using following module for this purpose.

LoadModule expires_module modules/mod_expires.so

I have added following lines in my httpd.conf file to set set the expire settings on the documents.

ExpiresActive On

ExpiresDefault "access plus 1 year"

By documentation, this should enable expiration on all the documents for one years, In response headers returned by web server, there are expire header and also cache control header with max-age attribute, But still when i refresh the page, request goes to server to fetch the file.

I presume these files should be loaded from cache only. Can you point what i might be missing?
