Behavior of traffic server on client connection timeout?
Hi,
I have ATS 4.2 configured as a reverse proxy for a HTTP upload service.
The flow is ATS -> HAProxy -> Origin server farm.
In records.config, I have:
CONFIG proxy.config.http.transaction_no_activity_timeout_in INT 60
CONFIG proxy.config.http.transaction_no_activity_timeout_out INT 60
Which I assume governs ATS behavior when there's been no activity (no new
bytes from user connection).
I did a test where the client connection is interrupted (by unplugging the
ethernet cable during an upload). However, ATS log does not show a timeout
after 60 seconds. Instead, once the upstream server detects a connection
timeout, it returns a 500, which gets logged by ATS.
I'd like to have ATS detect a client connection timeout, and then terminate
its connection to the origin server and log the event. How can I do this?

Also, note that ATS's implementation cancels the UA (client) side inactivity timer once the origin servers headers have been received. Perhaps, this may be what you are noticing.

Perhaps, in your test, since both the outbound and inbound are configured as 60 sec, the origin side (HA Proxy) may be occurring faster. You may want to set the origin side timer to higher than 60 sec and check.
