Thomas Jackson closed TS-3306.
------------------------------
Resolution: Not a Problem
Turns out there was a bug in the origin that was miscalculating the
content-length. Some clients (such as curl) will continue to use the tcp
session even if there is such a mismatch, but ATS doesn't-- which is more than
fair. I've fixed the test case, and can confirm that it is working as intended.
> Keep_alive_out not working
> --------------------------

> Key: TS-3306
> URL: https://issues.apache.org/jira/browse/TS-3306
> Project: Traffic Server
> Issue Type: Bug
> Reporter: Thomas Jackson
> Fix For: 5.3.0

> I *hope* that I'm just missing something very obvious, but as best I can tell
> keep_alive_out is not working on 5.0, 5.1, and master. At some point this
> worked as we vetted the feature when we rolled it out-- I think we were
> running 4.2 at the time.
> To show the issue I created a test
> (https://github.com/jacksontj/trafficserver/commit/f913b88666aef6502b8540149a60b2ce25853f9c)
> which shows the issue.
> In my test case there is a socket server which just returns a 200 OK
> keep-alive response with the body being the number of HTTP requests this tcp
> connection has seen. If you run the test you can see that it will always
> return 1. I thought this could have been some issue timeouts or something,
> but you can see in the output (below) that ATS immediately closes the
> connection to origin.
