Thanks Roland.

I tried treating them as footers to no avail. I still don't get access to the actual body of the response.

Here's the wire log. As you can see from below, the "data" portion of the response (which should be considered the body) is being skipped over to get to the headers. The problem is that attempting to grab the data as headers, footers or body is not working. It's like the method is throwing those lines away (but the wire output thinks they are header rows).

Sorry about the footer... I have no control over what the exchange server appends to my messages on my behalf...

I'm working with an API that returns the HTTP Response Headers after the response body. This confuses the HTTPClient and PostMethod into thinking that there is no body.

We have code to handle footers in ChunkedInputStream. However, this is the first time that I encounter footers in the wild, so maybe that code is buggy. Could you please post a wire log, including headers and content? Feel free to obfuscate any sensitive information and cut the contents.

Is there a way for me to get direct access to the response input stream so that I can parse it out myself?

You can hack through the code of course. The socket's stream is not accessible directly, because the ChunkedInputStream has to parse the "chunked" encoding. Trailers are only allowed with chunked encoding. If you have to hack through the code anyway, you should rather fix what is broken than work around what is already there.

Always funny to read these footers on mails sent to public mailing lists...
