simple workers.properties question (John Turner's how-to)

[Denise Mangano]

According to the how-to, I created the workers.properties file.  My
question is simple:
 
Is it ok to leave:
    worker.ajp13.host = localhost
 
or should I change it to:
    worker.ajp13.host = www.mydomain.com
 
In my httpd.conf my ServerName is www.mydomain.com, and in my server.xml
the Host name is www.mydomain.com
 
Thanks :)
