Redirecting domain to the main domain (hosting cost?)

[SirMax]

Hello Everyone,

I have the following situation.  There is main domain and a secondary domain that is related to the page on the main domain. I want to integrate the content of the secondary domain into the page on the main domain and redirect the secondary domain via 301 to that specific page.

As i understand I can do it via .htaccess using rewrite mechanism.

But the question is does it mean I have to keep paying for the hosting for the secondary domain? Because htaccess has to be located on the web server so I would need a hosting plan for it? Is that true? Is there any way around it?

P.S. to avoid any confusion - I am talking about hosting plan - not domain registration fees

The domain that I want to forward is registered at 1and1. They have an option to forward the domain through DNS settings. Will that option allow me to keep the PR juice that have accumulated for this domain. It is/was PR4 site.
