Standard HTTP error codes how?

Quick query,
When the proxy tries to access an invalid web site=20
and gets and error. It send the browser an error=20
webpage. The browser gets the web page but doesn't
get an HTTP error code so it's doesn't know the
error actually happened. Is there a way to get
standard HTTP errors back to the browser so it can
act on those and not just blindly display the error page?

E.g This is a problem for users that cannot get a=20
proper response from putting "microsoft" in the=20
address box. The cache sends back a web page and=20
the browser does no more but if the proxy is disabled
the browser gets a proper error and goes on to
lookup www.microsoft.com and brings up the correct
web site.

Could you please reply to me directly at markrogers@ozemail.com.au
Thanks.
