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.
