Oleg Kalnichevski commented on HTTPCLIENT-1877:
-----------------------------------------------
Neither zlib-flate, nor pigz, nor Java for that matter recognize the content as
a valid ZLIB stream. Just because some browsers can guess the format and
decompress it it does not make the response valid.
{noformat}
oleg@ok2c:~$ zlib-flate -uncompress < stuff.bin.zz
flate: inflate: data: incorrect header check
{noformat}
{noformat}
oleg@ok2c:~$ pigz -t --zlib stuff.bin.zz
pigz: skipping: stuff.bin.zz is not compressed
{noformat}
{noformat}
@Test
public void testStuffBin() throws Exception {
DeflateInputStream inputStream = new
DeflateInputStream(getClass().getResourceAsStream("/stuff.bin.zz"));
try {
byte[] tmp = new byte[1024];
while (inputStream.read(tmp) != -1) {
}
} finally {
inputStream.close();
}

> In the attached log, the issue occurs on second request.
> Removing Deflate from Accept-Encoding is a workaround, so issue is located in
> Deflate management, GZIP works fine.
