If you want a red alarm if you are able to retrieve the result, you 
probably want to use the HTTPSTATUS test of Xymon. From the man-page:
> httpstatus[=COLUMN];URL;okstatusexpr;notokstatusexpr
>     This is used to explicitly test for certain HTTP statuscodes returned when the URL is requested. The okstatusexpr and nokokstatusexpr expressions are Perl-compatible regular expressions, e.g. "2..|302" will match all OK codes and the redirect (302) status code. If the URL cannot be retrieved, the status is "999"

something like:
httpstatus=web;http://foo.bar.com/robots.txt;4..|[1-9]..

will try to retrieve http://foo.bar.com/robots.txt and put the results 
under a column titled "web". It will be green if the HTTP return code is 
anything in the 400s. It will be red in all other cases.
