The minimal example of the request handler used in my application is as follows:

	class StreamBufferReadHandler: public HTTPRequestHandler
	{
	public:
		void handleRequest(HTTPServerRequest& request, HTTPServerResponse& response)
		{
			auto streambuf = request.stream().rdbuf();

			char buffer[4096];
			streambuf->sgetn(buffer, sizeof(buffer));
			streambuf->sgetn(buffer, sizeof(buffer));

			response.send();
		}
	};

I.e. the following assertments are true:

• std::ios::rdbuf is used to get the data from the stream;
• getting data from std::ios::rdbuf may be requested after EOF was already hit once.

The code works properly when fixed-length request is received, but hangs with chunked-encoded one. Looks like the main problem is HTTPChunkedStreamBuf does not save EOF state inside, as HTTPFixedLengthStreamBuf does.

Is it a bug or is the behavior expected? May it be fixed?
