I am trying to implement mod_disk_caching. i wrote a php code as shown in the example of the tutorial i was following.

i fired the following in the terminal

a2enmod cache a2enmod disk_cache

/etc/init.d/apache2 force-reload

then in the php code

"; ?>

now i tried running it using firefox. In the first execution i got the following timestamp. 1308643975 here, when i press refresh, the timestamp changes (as the file is reloaded from the server) and remains the same when i click the link again (as the file is retrieved from the cache).

Now i am trying the same with IExplorer. As per my understanding, the timestamp should be the same as the subsequent request for the file will be retrieved only from the cache. But i got a different timestamp.

Can anyone explain me the reason for this? Why is it giving separate timestamps when the browsers are different?

Thanks and Regards, AMJ
