Watir will raise WatirNavigationException if it receives certain urls -
it does a regexp on the url looking for
shdoclc.dll ( if I remember correctly)
This is the exception that gets raised
irb(main):013:0> ie.goto('ggg.cddfdom')
Watir::Exception::NavigationException: Cannot find server or DNS Error

The "rescue" technique was documented in old versions of the Watir
documentation. It is a bad idea and had been removed from the version
currently posted to the website.
Strictly speaking, this was never a Watir feature. Rather, rescue is a
Ruby
feature, which doesn't really help with what you are doing here.

The fundamental problem is that an "error" at the http-protocol level
(like
a 404) is not a Watir error. It won't raise an exception.
Why? Because from a user level (which is the level that Watir works at)
there is no error. The browser shows a page -- maybe it is a 404 page.
You will have to add code to check to see if you got a page that was
different from what you expected. Sometimes a 404 is what is supposed
to
happen.
