Please indulge me in a Mongrel clustering noob question.

I just got mongrel clustering set up, is there any way for me to know  
(via log files, etc.) which instance of Mongrel serves up a given  
request?

URLs if appropriate, please.

Thanks,  
Wes

If you use the SyslogLogger gem to log via syslog then you get pids in  
your log files.
