Subject Re: [users@httpd] apache 2.2.3, virtual host and balancer manager. Only one balancer can be monitored
Date Wed, 20 May 2009 22:18:55 GMT

I have read doc again, and after testing a little I think I should move "Location" directive
to a different file (outside vh definition), in order to make "sense", but results are the
same...

Thank you again.
