Yes, this is where it all happens.

The important part of %U is found further down
case 'U':
p = r ? urlCanonicalClean(r) : err->url ? err->url : "[no URL]";
break;
this calculates what %U should be replaced by. Translated to english the
above logics is
If there is a request then use the URL from the request
else if there is a URL registered in the ErrorState object use that url
else "[no URL]".

extacl_user is maybe not what you are looking for. This is the username as
returned by external_acl_type, not the username from authentication.
There is quite many kinds of usernames in Squid. The current Squid-3.0
sources have the following different username concepts:
* Username from URL, as in ftp://user:[EMAIL PROTECTED]/
* Username from authentication
* Username from IDENT lookup
* Username from external acl lookup (external_acl_type)
* Username from SSL certificate
As each have somewhat different meaning each is accessed differently.
Examples on how most of these can be accessed can be found in
ClientHttpRequest::logRequest() and clientPrepareLogWithRequestDetails()
(both found in client_side.cc) where the information is prepared for
logging in access.log.
