ME Hosting Chat Questions

I have an account with you under the domain antioxidantbioscanner.com. Under the public_html folder I have 3 groups of subfolders that all contain separate content. They are each, in effect, their own web sites. The path for each of these 3 "home pages" for these 3 web sites is laid out like this:

public_html/LifePak/lifepak_home.htm

public-html/Pharmanex/Pharmanex_home.htm

public_html/Scanner/biophotonic_scanner_home.htm

The domain that the account is listed under is antioxidantbioscanner.com. This domain is currently pointed at the parent directory. You can see where this domain is pointing by typing the domain into your browser or by clicking here.

Here are my my questions. How do I get this domain, antioxidantbioscanner.com, to point to the web page public_html/Scanner/biophotonic_scanner_home.htm which is the appropriate "home page" for this domain so that when people type in www.antioxidantbioscanner.com, they arrive here?

And how would I get 2 other domains, say www.lifepakinfo.com and www.pharmanexinfo.com to point at the home pages

public_html/LifePak/LifePak_home and
public-html/Pharmanex/Pharmanex_home?

For example, the true URL path that gets you to the Scanner home page currently is:

www.antioxidantbioscanner.com/Scanner/biophotonic_scanner_home.htm

You can go to this scanner home page by clicking here.

How do I change where this domain is pointing so that if someone types in www.antioxidantbioscanner.com, they are taken to this scanner home page?

Regarding ME Hosting Redirects Function

As far as I can tell, the redirect function in the Control Panel of ME Hosting can only redirect from a location within the web site to another location… either within the same web site or to another location on another server.

It can't take a domain name from outside and redirect it to a URL inside the web site that is hosted by ME Hosting.

For example, when I tried to redirect antioxidant.com to the actual home page for that antioxidant information on the server (antioxidant.com/Scanner/biophotonic_scanner_home.htm), it didn't work.

So, the question remains… how do I take a domain and point it to a specific URL location on a ME Hosting.com server? Is this something that needs to be handled on the registrar's end?
