When testing the site using yahoo YSLOW it says above message. So I don&#39;t know how to add expire headers. Any help would be appreciated?

Add Expires headers

I&#39;ve looked around but haven&#39;t been able to figure out if I should use both an ETag &lt;strong&gt;and&lt;/strong&gt; an Expires Header &lt;strong&gt;or&lt;/strong&gt; one or the other.

What I&#39;m trying to do is make sure that my flash files (and other images and what not only get updated when there is a change to those files.

I don&#39;t want to do anything special like changing the filename or putting some weird chars on the end of the url to make it not get cached.

Also, is there anything I need to do programatically on my end in my PHP scripts to support this or is it all Apache?
