possible to use different domain names s aliases

[wpoolman]

is it possible to use different domain names as aliases?

i have 4 domains, these should point to the main domain name, is that possible? can i add

1 domain as main domain myweb.com

2 domain as alias like oklahome.biz

3 domain as alias like boomle.net

4 domain as alias like homerlyric.org

is that possible in plesk 8 ????

or can only use same domain name, where the tld is different as aliases??

cheers
