#1665: Wrong behavior of timeout_req
-----------------------+----------------------
 Reporter:  sorinescu  |       Type:  defect
   Status:  new        |   Priority:  normal
Milestone:             |  Component:  varnishd
  Version:  4.0.2      |   Severity:  normal

-----------------------+----------------------
 The documentation defines timeout_req as:

 Max time to receive clients request header, measured from first non-white-
 space character to double CRNL.

 The problem is that the code measures the time from t_idle, which is
 either the moment when the connection was accept()ed (which is fine) or
 the time of the last activity of the previous request on the same
 connection (which is wrong). This leads to prematurely closing the session
 with RX_TIMEOUT.

 I'm attaching a patch that fixes the problem for me.
