// Permanent redirection
header("HTTP/1.1 301 Moved Permanently");

Save, exit and upload to webserver.

To above example, when browsed from internet browser, redirects an old domain to a new domain. This is very useful on moving from one domain name to another domain permanently. Alternatively, you can append any default HTML file to new domain location to suit your needs.

# vi

#!/usr/bin/perl -w
use strict;
print "Status: 301 Moved Permanantly\n";
print "Location:\n\n";
