2 domains on 1 site?

Redirect to the main site?

I can only one domain insert into the main stettings of the site by host. (administration/settings_main)

Where must be the second domain insert, that the site work with the 2 domains correctly?

this!

What you want makes no sence. Visitors will be confused and Google will hate you for double content...

Is it something like this, that you're looking for, Harlekin - Two sites and same member database. It's called "Multisite"!

P.S. You can find, and download, the V7-Manual, refered to in the post, here: Official PHPFusion 7 Manual 1 (The "Multisite" guide starts at page 181 of the PDF-file)

No, i do not search for multiside. I have from my hoster two domains on my webspace. The first domain is a .de domain and the second domain is a .com domain.

I search for a way to have the both domains on one website. Without redirecting from .com domain to .de domain.

And what result are you expecting from this?
What is the practical purpose of having 2 domains running as 1 site (is that even possible)? And why don't you just add all the functions you need to one of the domains?

I don't understand what you want, but I maybe you can give us an example of such a site, running 1 site on 2 domains? The more we know about what you want, the better chance you have of getting a push in the right direction! :)

Some reasons for more domains on one site:

- Nobody can use the same name from the .de domain in a .com or org or net domain.
- Many people, in germany, when typing in domain names, instinctively type a ".de"
- Many people, when typing in domain names, instinctively type a ".com"
...

The only way for what you want IS a redirect.
Either by a .htaccess on one of the websites, or as a default redirect by host (set webdirectory in admin-cp of your hoster e.g.)

For redirect by htaccess look here: http://www.htaccessredirect.de/

I wonder why you didn't ask in any german forum?!

Ignore the above comments.
What you are looking for is called domain alias.
If you use CPanel search for Parked Domains.
