Ming Fai commented on HTTPCLIENT-796:
-------------------------------------

I've encountered the same problem with core 4.0beta1. Looks like IIS sends out \
incorrect chunk header.

by 
 - disabling the TestChunkCoding.testCorruptChunkedInputStreamNoClosingChunk, and
 - at ChunkedInputStream, changing from
{code}
        if (i == -1) {
            throw new MalformedChunkCodingException(
                    "Chunked stream ended unexpectedly");
        }
{code}
to
{code}
        if (i < 0) {
            return 0;
        }
{code}

I'm able to get rid of the exception and able to download a malformed chunked \
response. I could provide a patch if you want. I suppose httpclient should handle \
malformed chunked response, but i'm not sure if it should be configurable like the \
original patch.
