Page Caching

[ryy705]

hello,

 

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.

echo date("H:i:s");

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.

You should consider server side cache as opposed to client side, this way you control when the cache is updated, and not by a user forcing a refresh or clearing cache etc.
