A better approach to solving the content-type problem others mentioned is to cache the response headers along with the response data. Then when serving content from the cache, apply all the cached headers to the response. This ensures responses served from the cache are identical to the originals.
This approach works very well with the client cache control headers as well, as you can specify a page expiration that is sent to the web browser, and also controls the expiration time in the cache filter.

    That is a very good idea. I tried doing this but underfortunately I don't see any way to get at the underlying headers using a HttpServletResponseWrapper.

    Any idea how to implement this?
