last header in response does not get parsed

[peter12s]

In AsyncHttpClient.cpp at line 635 you initialize the String headerData with context->responseBuffer.substring(0, headerEnd) before passing it to parseResponseHeaders.
This means that the end of the string headerData does not contain '\r\n'.
In the function parseResponseHeaders you search for '\r\n' in order to find every header. So the last header is missed in this case.
Therefore I think line 635 should be as follows: String headerData = context->responseBuffer.substring(0, headerEnd + 2);
