Subject [users@httpd] Re: Problem with mode_expires module
Date Wed, 15 Sep 2010 09:17:27 GMT
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?
