Image caching prohibited at the server level? 2002

A programmer friend just approached me with an odd problem which I couldn't explain. Basically what he's seeing is this:

On Server A, you can do a search and the results page will load and in the log you'll see the requests coming in from the client for the navigation image files. Then you can hit next to go to the next page of results and you won't see the image files re-requested since the browser already has them.

On Server B, when you search the behavior is the same until you hit next. Then the next page loads and requests all the navigation image files as though it was the first time it had ever heard of them. And if you hit next to see the 3rd page of results, again it will request all the navigation images.

He's seeing this in the same browser, so it appears to be an issue on the server not the client side.

Anyone got any idea what's going on?

One environmental note: Server A & B are, theoretically, running exactly the same proprietary web server which is integrated with the searching software.

Blog (noun) A weblog or similar brief journal usually containing links and commentary thereon. Term coined by Peter Merholz.
Visit Typepad or Blogger to start your own. (I began with hand coding, then switched to Blogger when it first became available, then to Movable Type when I wanted more control over my weblog and to have it hosted at a place of my choosing (Hurricane Electric). Now I use Typepad, built by the same folks who made Movable Type and I love it).
