1. Configure your AccessLogValve to print "User-Agent" header of the
request (%{User-Agent}i ). This way you will know what requests come
from wget and how fast they are served by Tomcat.
2. Make sure that the page contacted by wget does not use sessions. If
each request creates a new session it would be a waste of resources.
You can include session id into AccessLogValve configuration: %S
