The client is making a range request 0-1023 to the http server. It prefers gzip compression with Accept-Encoding: gzip;q=1.0, identity; q=0.5, *;q=0 in the request.
What would be the content-length in the response header? Will it be 1024 or the size of the compressed data.
Thanks,
Short version: it's the compressed size.
RFC 2616 has this to say (amongst other things) about Content-Length:
"Applications SHOULD use this field to indicate the transfer-length of the message-body, unless this is prohibited by the rules in section 4.4."
Section 4.4 (Message Length) says this about transfer-length:
"The transfer-length of a message is the length of the message-body as it appears in the message; that is, after any transfer-codings have been applied."
http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.4
The actual content length depends on the transfer encoding and data: If you use identity, no compression is applied and the content length is 1024; if you use gzip, the actual content length depends on the data that is to be compressed.
