Pulling PHP pages from the cache?

[Anon]

I have a PHP page that is generated dynamically, but doesn't change very much.

For example, it generates a table of thumbnails of images, based on a variable. When I want to add more thubmnails I just change the variable.

So hence, the page only REALLY changes when I actually add thumbnails, which only happens maybe once a week.

However, I get the feeling that whenever a browser accesses the page it's getting the page over again from the server and processing it again. I'd rather have the remote browser pull the page from cache instead of calling my server again.

Is there anyway to set up the server to accomplish this or use some wacky comination of meta tags and php stuff?

Thanks,

Tim

Tim,

I'm not sure if spending money on a solution is an option you're even considering in this case, but the Zend Cache maybe what you're looking for here. I don't know if a free equivalent exists, but it maybe something to look into. Here's the link:

Hope this helps!!

Cheers,

Geoff

Did you tried to put a cache directive in your page.

You can use the header function in PHP to send a cache directive at a desired date.

ex
<?
// Compute the desired date : today + 1week ( 3600247 )
$expired=gmdate("D, d M Y H:i:s",time() + (3600247))." GMT";
header("Expires: ".$expired);
...
?>
