Many of you are probably familiar with the following terms applied to Domains - Fowarding, Aliasing, Masking, and Parking.

Which term would apply to the following scenario/setup?

I would like to register my site and have another site forward to an area of mine.
For example -
(fictitious names used)
mysite.com would be my site.
mysite2.com would be another site.

When a user enters mysite2.com in their browser, I want it to go to mysite.com/site2/index.jsp.

You might be wondering why I want my site to work this way. I'm planning to setup my site and have my customers sites run under mine. I will register their domain, but each one will redirect to my main site, where their data/web pages are stored.

1) What is the proper term applied to that 'forwarding' scenario? Is it domain forwarding?
2) Should I expect a web host provider to allow me to specify that sort of redirecting?
3) Or is that something I should expect a domain registering company to permit me to do?
4) If a domain registrant or web host provider doesn't permit it, what can I do to work around it?

Thanks in advance for your help :)

If it was masking they would go to mysite.com/site2/index.jsp, but the address bar would show mysite2.com.

1) I believe you would call this forwarding

2 & 3) This would need to be done at the host not the registrar. Control panels such as cpanel and plesk will allow you to set up redirects pointing to a specific URL.

4) Possibly through a .htaccess file, not sure.

If your host uses cPanel for your site management, it can be easly done under "Domain Management". If not, .htaccess possibly is a right solution, cmiiw :D.

Thanks for the replies everyone!

I'm glad that its something that will be easy to specify/setup...that is if I get cPanel with a host provider once I sign up. Otherwise, I figure I could workaround it by specifying mysite2.com/index.jsp to redirect to mysite.com/site2/index.jsp in the Meta tag... right?
