selectively caching

[jhughes96]

Hi,
I have apache in front of an application server for caching
purposes (using ProxyPass). Now I only want to cache GIFs,
JPEGs, CSSs .JS etc and have no control over the expiry
information issued from the application server (which would be
happy for everything to be cached). Apache would quite happily
cache everything but I want to be selective.

To go about the problem a different way, the URLs I don't wish
to cache usually contain a '?' - I have tried to use the nocache
directive to search for this but it doesn't seem to work.

Any ideas?

regards

Joel
