Can't you use chunked mode content-transfer-mode with compression?


Yeah, you can use chunked transfer with compression, and I thought I could decompress, process, and recompress chunks of a message body in a stream. False assumption. The entire message body is compressed before it is transfered, and individual chunks can't be decompressed.

Since I want to avoid the possibility of being caught holding a bunch of large message bodies in memory, I think I will avoid accepting compressed messages from the origin server. I will just support compression in addition to chunked transfer from proxy to client.

Thanks for helping.
