Hi,
Currently, libcurl rejects responses with "Content-Encoding: compress"
when CURLOPT_ACCEPT_ENCODING is set to "". I think that libcurl should
treat the Content-Encoding "compress" the same as other
Content-Encodings that it does not support, e.g. "bzip2". I have
attached a patch for this.
Regards,
Michael
