If you do this you’re going to find deployments very hard as clients won’t check for new files for a day after the last hit.

Ideally what you want is to use E-Tags or timestamp your files URL to force client cache (e.g image1.gif?200904301147)

Hi Neil, eTags is exactly the next topic I’ll be talking about. I find that ySlow helps heaps to detect this kind of things, and to be honest, I didn’t know about eTags till very recently when I decided to set up my own server.
