Re: Query on access log for entry of %T

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
Thanks for your time and paitence.
I am not worried about the TimeOut value as I am not using mod_cgid.so.What I understand from your explanation is even if the Client times out before the response comes in time,Apache can send the response back to the client.Also this is the time which it actually took to serve the request?If I am not correct let me know.

But just curious about the Client side, so when it gets a response from the webserver for which it has timed out, the response may be discarded also.Let me know your views.
Thanks
Arnab

It depends on what Apache's doing with the 25 seconds (proxy, cgi,
reading a file, running php code, proxy).

Apache doesn't limit itself to 25 seconds of running your CGI or 25
seconds of trying to read a file from a dead network drive.

>From the manual:

The TimeOut directive currently defines the amount of time Apache will
wait for three things:

  1. The total amount of time it takes to receive a GET request.
  2. The amount of time between receipt of TCP packets on a POST or
PUT request.
  3. The amount of time between ACKs on transmissions of TCP packets
in responses.

No.
