Check for string on web site failing

["Smith, Cathy" <cathy.smith (at) pnl.gov>]

Folks
 
I set up a check to match a string for a web email server in my bb-hosts
file to ensure that the page was loading properly.  The check looked
like:
    
10.10.5.173  foobar.pnl.gov # class:server
cont=WebMail;https://foobar.pnl.gov;WebMail.Access
 
The check worked fine until this past weekend when the email server was
migrated from Exchange 2003 to Exchange 2007.  Now instead of an
index.html file being downloaded, I get a SGML document.  Even though
the same string is in the title tag in the document, the check fails.
Can someone suggest a way to check that the page has properly loaded?
 
Thanks for your help.
 
 
Regards,
 
 
Cathy
