[users@httpd] Problem with mode_expires module
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?
Regards,
Vijay Shanker Dubey

I clear my browser cache daily, and have my browser set to ALWAYS get
the file from the server.
your caching will never stop handing me the files every time I access
the server.

This is usually configurable in the browser.

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?
