Firefox doesn't seem to have this problem, so unfortunately this is a Safari 3 only issue.

Yeah PHP can send out appropriate headers to tell the browser to cache 
the content delivered. You just use header() with appropriate 
Cache-Control and Pragma etc. headers. There are lots of good resources 
out there on how to do this so just google around now you know the 
concept :)
