Yes, by looking at the headers of the browsers request & then sending back approriate ones using the header() function you should be able to have full control over caching. Off the top of my head I'm not certain of exactly what headers are involved each way (status, if-modified, last-modified, e-tag, etc..) but the tools are there.
