Do you mean instead of the browser using the cached page ?? If so you can do this using php's header function

yes, and how can I do that?

[shedokan]

I found this script:

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1

[Distant_storm]

That would cause no cache to occure although this can be abit tough on your server if you get alot of hits in one go then it would have been easier for the browser to get the cache'd page. you can do the following

 

Set an expiry for your pages to be cache'd and then updated after that date.

set when the page was last updated which is then checked against another value to see if the new page shoud be retreived from the server.

 

 

If you don't want your pages cached at all then

 

 

header ("Last-Modified: Wed,21 Nov 2006 01:41:00 GMT");

 

header ("Expires: Mon,26 Jul 1997 05:00:00 GMT");

 

header ("Pragma: no-cache");

 

header ("Cache-Control: no-cache");

Do you have a script or an example I could see?

to learn and use.

I want them to be chached but only if it's nessecary

What exactly are you updating and how often do you update your site? I am trying to grasp what you are doing.

[shedokan]

about each day or so, and I'm updating databases and pages.

[phpQuestioner]

is it mostly text or images or a combination of both?

[shedokan]

combination of both and database.

[phpQuestioner]

I do not see how your pages are catching that much if your only updating your content once a day. You could create an JavaScript or AJAX script that would re-query your page at specific time. I would just create php no-cache header and you could try to create a javascript preloader for your images, but the no-cache header may not let them be preloaded.

But then I will have a lot of bandwidth used...
