I can't see how you could have any meaningful caching at all if the content is varied by IP address, unless you had the IP address in a header and did some clever caching of variants. In this case you'd probably not use the cache at all for this part of the URL space. > Another example is > changing protocol behavior when communicating with the client. What protocol behaviour would change, can you give an example? Regards, Graham --
