On your advice Tollef I tried the following test configuration and sent requests using lwp-request to change the user agent string.


sub vcl_fetch {
	set beresp.ttl = 10s;
        set beresp.grace = 60s;
}

sub vcl_recv {
        if ( req.http.user-agent ~ "foo" ) {
                set req.grace = 30s;
        } else {
                set req.grace = 5s;
        }
}



But that's just expiring content for either user-agent case according to the ttl. I think it must be the saint mode, but I don't understand how to set that for a specific user agent, as I read the documentation I should use grace mode OR saintmode and the parameter is set on the beresp object. 

I missed something I'm sure...
