[squid-users] not all lines of access.log contains the username

[IT HIA service]

Hi everybody,
We make authentification with ncsa (username and password). But in
access.log, we don't see on each line the username. The Ip adress of the
computer is present. But the username appears only with CONNECT ...:443.
For a GET, the username is not written. In this example, "dupont" is a
username.
Is it possible to have the username present for each line in the file
access.log ?
 
Thanks for your help
