Retirado do pod do modulo CGI.pm:

GENERATING A REDIRECTION HEADER

          print $query->redirect('http://somewhere.else/in/movie/land');

       Sometimes you don't want to produce a document yourself, but simply
       redirect the browser elsewhere, perhaps choosing a URL based on the
       time of day or the identity of the user.

       The redirect() function redirects the browser to a different URL.  If
       you use redirection like this, you should not print out a header as
       well.

       One hint I can offer is that relative links may not work 
correctly when
       you generate a redirection to another document on your site.  This is
       due to a well-intentioned optimization that some servers use.  The
       solution to this is to use the full URL (including the http: part) of
       the document you are redirecting to.

       You can also use named arguments:

           print 
$query->redirect(-uri=>'http://somewhere.else/in/movie/land',
                                  -nph=>1);

       The -nph parameter, if set to a true value, will issue the correct
       headers to work with a NPH (no-parse-header) script.  This is 
important
       to use with certain servers, such as Microsoft IIS, which expect all
       their scripts to be NPH.
