I think the Content-Transfer-Encoding header may be causing the problem. (More accurately,  a libUrl bug is causing the problem). A quick check in older libUrl code shows that lineOffset("Transfer-Encoding:",<string>) is used to find the Transfer-Encoding header. That will pick up the Content-Transfer-Encoding header instead. That would explain what you're seeing.

Although it seems like a bug in libUrl, the "Content-Transfer-Encoding: text" header seems unusual. "text" isn't specified as a possible value here. (Typical is base64, binary, etc.) Are you doing anything that might cause that to get set?

As a possible workaround, what happens if you specifically set the "Transfer-Encoding: chunked" header early in the php script. If it causes it to come before the "Content-Transfer-Encoding" header, I'd guess it would work.

Cheers
Dave
