I'm using BOSH (from Strophe on Chrome 42) into an OpenFire 3.10.0 server. Small packets are working fine. But as packet sizes get larger, around 27K we start to see OpenFire returning Transfer-Encoding: chunked. That works (although is not supposed to be happening based on recent fixes). However, once the packets get a bit larger, we are frequently seeing errors in Chrome where it is reporting: ERR_INVALID_CHUNKED_ENCODING. From what I understand, this probably suggests that Chrome thinks that the chunks are not being properly terminated with CRLF.
I saw OF-885 in 3.10.0 and think that perhaps this may be related.
