BUG/MINOR: http: Be sure to process all the data received from a server
When the response body is forwarded, if the server closes the input before the
end, an error is thrown. But if the data processing is too slow, all data could
already be received and pending in the input buffer. So this is a bug to stop
processing in this context. The server doesn't really closed the input before
the end.
As an example, this could happen when HAProxy is configured to do compression
offloading. If the server closes the connection explicitly after the response
(keep-alive disabled by the server) and if HAProxy receives the data faster than
they are compressed, then the response could be truncated.
This patch fixes the bug by checking if some pending data remain in the input
buffer before returning an error. If yes, the processing continues.
