      Description

      While trying to workaround TS-3439 I decided to test out the connect retries option. During testing I found a case where it should not retry where it is.

      The scenario is as follows:

      • ATS makes a connection to an origin
      • the origin acks the entire request
      • the origin starts to send back a response (lets say first line of the header)
      • the origin sends an RST

      In this scenario ATS will re-connect to the origin, which is bad since we have already sent the request (and we aren't sure if the URL is re-entrant).

      Test case: https://github.com/jacksontj/trafficserver/commit/28059ccb93f9fb173792aeebf90062882dfdf9d5#diff-06f9ddbe6cc45d76ebb2cb21479dc805R182
