Forcing Cache?

[keyplyr]

I have a user-side utility which displays 5 different images in various combinations according to how the user decides. Users typically spend 5 or 10 minutes using this utility, resulting in many requests for the same images.

Almost daily I get a user who has changed IEs settings to "always ask for the latest copy of..." instead of calling these 5 images from cache. Eventually, the redundant requests for the same files triggers my host's limits and my logs are filled with "403 - denied by server configuration"

I am not going to rewrite a very large and complicated script that runs the utility, but I am searching for a reasonably resolution to 50kb of error_logs every morning.

And yes, I do have my expiry set to:

ExpiresByType image/gif A2592000
ExpiresByType image/jpeg A2592000

Thanks

Why expire them at all?

Move them to a cheaper bandwidth host. Do a "properties" over the logo here... I save 50gig of bandwidth a month by doing that.
