Subject Re: Re[2]: [users@httpd] Testing if a Webserver is down
Date Thu, 31 Oct 2002 12:17:14 GMT
I use this simple perl script to check if a webserver is reachable,down,
or up but don't answer any http request, look on the attachment, you just 
need to change the $Host variable to your webserver name, and the interval
of testing.
