Using deflate for a response via HTTP

See more:

C++

Hi all,

I have problems when trying to apply a "deflate" decompression. I want
it to work on content which I received via HTTP with the response header
field "Content-Encoding: deflate".

I have tried the solution suggested by Heikki Pora using
CEZCompressor::DecompressL() but this leaves with KZlibErrData. Also, I
have seen that my received data does not suit the specification for a
Zlib data stream according to RFC 1950. See below a complete hex view of
my data.

Questions:
I would expect the data received via the HTTP to be like the ZLib
specification. Is this not the case?
Am I mixing HTTP's deflate with ZLib?
Does anyone have an example of how to decompress data from a "Deflated"
HTTP response?

Thanks for any hints
and Best Regards,
