Yes.

The response time / duration in Squid logs is from the time the request 
was received by Squid (full headers seen) until the last byte of the reply 
has been queued for write to the client.


Time not included is the time it takes for the client to send the request 
headers to Squid, or for TCP/IP to transmit the last bytes of the 
response.

[squid-users] Advise on response time on custom logformat and duration in native log

[squid squid]

My setup in an Intranet environment is as follows:

Client -- Squid Proxy A --Squid Proxy B -- Destination apps

The above is such that client cannot communicate with Squid Proxy B and need 
to use Squid Proxy A to relay access of Destination apps thru' Squid Proxy 
B.


On Squid Proxy A, I have implemented Custom LogFormat and the response time 
(ie. %tr) showed a value of 3562. On Squid Proxy B, I have native log and 
the duration showed a value of 3550. The 2 values are based on client 
accessing the same object passing thru' Squid Proxy A to Squid Proxy B and 
then to Destination apps.


I would like to know the following:

1.  whether the duration field in navtive log has the same meaning as 
response time in Custom LogFormat???


2.  based on the above setup, the response time in Custom LogFormat is the 
response time from where to where (ie. from Squid Proxy A to Squid Proxy B, 
from Squid Proxy A to Squid Proxy B to Destination apps)???


3.  based on the above setup, the duration in native log is the duration 
from where to where (ie. from Squid Proxy A to Squid Proxy B, from Squid 
Proxy B to Destination apps)???


Thank you.
