In that case, you could use the "proxy" feature of the Hobbit HTTP
testing. Setup a web check like this:

10.0.0.1 hobbit.foo.com # ~cont=squid;http://proxy.foo.com:3128/http://hobbit.foo.com/hobbit/;Hobbit

What this does it to define a web content check. It will basically
request the URL http://hobbit.foo.com/hobbit/ and look for the text
"Hobbit" in the response. BUT - it will send the HTTP request to the
proxy at http://proxy.foo.com:3128/ instead of directly to the 
webserver.

You'll get two status columns from this: A "squid" column that goes
red if the response from the webserver does not include the word
"Hobbit"; and an (extra) item on the "http" status column.

The "~" at the front of the test is to make sure that the "squid"
column goes red when the proxy request fails - if you leave it out, 
then only the "http" column will go red - the "squid" column will 
go clear.

The only caveat is that it will *also* go red if your webserver 
stops, or if the webpage doesn't include the word "Hobbit". But
since all of this runs on the same box, there's a fair chance
that you'll notice this.

I've put this setup on my own demo site at http://www.hswn.dk/hobbit/
in the "Servers and Networks" section (host voodoo.hswn.dk has the
"squid" column).

One final note: The proxy feature does not support testing of
https (SSL) URL's - it must be a plain http URL.
