I am trying to experiment with page caching. I would like my page to be cached by the browser for 15 mins. Because the page content does not change much but it downloads thousands of the same records from the database every time the page loads.
I am generating the following header:
<meta http-equiv="Expires" content="Mon, 21 Sep 09 14:26:47 +0000" /> <meta http-equiv="Cache-control" content="private" />
with the following php code:
gmdate(DATE_RFC822, (mktime() + 900));
I am also printing out the the current time on the page to check if the page is really being cached or not.
It is my understanding that the time would not update on the web page if the page is really being cached.
Unfortunately it's not.
Kindly help. Any advice would be appreciated.
