Hello everybody,

 

So basically I've ran my site through ySlow and it has informed me that I should add Expires headers to some of the elements on my page to help with the caching. The page is mainly static content currently hosted on an Apache2 server.

 

If it helps at all the site is here.

 

I'm not really sure how you alter the HTTP header information but from what I have read I should use mod_expires module of Apache2 to set the Expires header.

 

Has anyone had any experience in this who could tell me what steps I need to take to implement the changes. Any advice would be greatly appreciated.

You could try this, it sets a week long expiry date:

 

<?php header("Expires: ".date("D, d M Y H:i:s", strtotime("+1 week"))." GMT"); ?>

 

It will need to be at the very top of your header code before any HTML/output to the page.

What about using the Meta Data 'expires' tag? or is this out of date now?

 

<META HTTP-EQUIV=Expires CONTENT="Thu, 29 Jun 2010 16:18:42 GMT">

Actually this article looks pretty damn helpful on the matter http://www.mnot.net/cache_docs/

 

In which case ignore my comment above.
