Transfer Encoding must be removed when caching, when transforming, when interpreting the body, or when transcoding to a hop with different negotiated Transfer-Encoding type. There is a very limited set of middleware (essentially just SOCKS or VPN tunnels) which can avoid it. All the rest have to implement the encoding. > Intermediaries are forbidden to decompress gzip content-coding to > look > into the content? Intermediaries are forbidden to change > Accept-Encoding and Content-Encoding? Why do you insert this word "are forbidden to"? It is a *performance* loss issue, not a permission one, for the large majority of intermediary types which do not need to touch the entity integrity in any way. Just look at how many of the transforming proxies that do content filtering find it necessary to force identity encoding from servers just to operate at any reasonable speed. AYJ
