  Then you deleted it.  The configuration items are in the default
proxy.conf file, with documentation.

  Also, the client may time out.  You can't control that.

  That's what the debug log is for.

  That shouldn't happen.  Please try the v3.0.x branch from git.

  It may be a bug.  And yes, the server is SUPPOSED to be anal about
timeouts.  That's what timeouts are for.  The alternative is to lie to
people.  "This timeout is for situation X, but if something happens
after the timeout, that's OK, too"

  There is no reason in heaven or earth for FR to ignore documented
