How do I redirect to another page?

Instead of sending back a Content-Type as the headers of your reply, send back a Location: header. Officially this should be a URI: header, so the CGI.pm module (available from CPAN) sends back both: 

    Location: http://www.domain.com/newpage
    URI: http://www.domain.com/newpage

Note that relative URLs in these headers can cause strange effects because of ``optimizations'' that servers do.
