Place this meta script in your page you want to redirect:
meta http-equiv="refresh" content="0;url=http://WWW.DOMAIN_NAME.COM/INDEX.HTM(L)"
(Change WWW.DOMAIN_NAME.COM to the other domain name and INDEX.HTM(L) to the name of the other domain's index file. Surround the script with right-left arrows<>.)
You can also use .htaccess to redirect the domain by placing the following in the .htaccess file:
Options +FollowSymLinks RewriteEngine on RewriteRule (.*) http://WWW.DOMAIN_NAME.COM/$1 [R=301,L]
(Create the file if it does not exist in the root folder of the old website (where the index file is located) and change WWW.DOMAIN_NAME.COM to the other domain name.)
