How do you force multiple aliases to resolve to one URL?

[pacified]

I've searched the Internet far and wide for a solution to this problem, and have found none. Maybe I'm just stupid (which I'm hoping) and you all can help me.

I'm running Tomcat 5.5.8. I have multiple virtual hosts running.

Some of the virtual hosts have aliases, for example like this

<Host name="bobjones.com">
<Alias>

http://www.bobjones.com</Alias>

<Alias>

http://www.bobjones.net</Alias>

<Alias>bobjones.net</Alias>
.
.
.
</Host>

My question: how do I force all requests to one of the aliases to go to the URL I put in the Host name="" area?

How do I force a user who goes to bobjones.net to get auto-redirected to bobjones.com?
