Susan Hinrichs created TS-3189:
----------------------------------
Summary: Do not start reading data on server to user agent tunnel
too soon
Key: TS-3189
URL: https://issues.apache.org/jira/browse/TS-3189
Project: Traffic Server
Issue Type: Bug
Reporter: Susan Hinrichs
The original logic would set up a do_io_read for max_int in
HttpSM::attach_server_session.
However, at this point there still may be things finishing up in the user_agent
to server tunnel (for posts). We were seeing occasional cases of the EOS for
the tunnel to user_agent communication being incorrectly delivered to the
consumer of the user_agent to server tunnel.
It is sufficient to set up a 0 length read in HttpSM::attach_server_session.
This will enable the correct handlers to deal with inactivity timeouts. Then
we can setup the real read in HttpSM::setup_server_read_response_header() after
we know that the user_agent to origin server tunnel has been taken down.
