It is possible, but difficult to do unless you can read the body and set it aside somewhere. Which again imposes an arbitrary (for the client) limit. Experience shows that this leads to design of clients that work will in developments, but then encounter requests usage/sites/servers that have other limits and break. If Apache accepts body lengths of up to 64KB (or something configurable) and some other server implements 8K and some third 1MB, how will that help design of a client that, for some reason, *wants* an upgrade to succeed? //Stefan
