I think you should be reading the mod_cache pages rather than mod_proxy.
Whether and when mod_cache will cache pages depends on the HTTP request
and response headers, so if it doesn't work with your backend
applications, then a bug report is in order.

Someone mentioned mod_rewrite, but I suspect that anything you could
usefully do with mod_rewrite here would be working around some
underlying defect.
