How to redirect one domain to another

问题

I have two domains:

www.example1.com/ --> IP=1.2.3.4
www.example2.com/ --> IP=1.2.3.4 (same IP for both domains)

I want all requests that go to www.example2.com/* to access the requested page. I want all requests that go to www.example1.com/* to redirect to www.example2.com/*. How would I do this in apache? As now I am currently doing this in javascript.

回答1:

put this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^(www\.)?example1\.com [NC]
RewriteRule ^ http://www.example2.com%{REQUEST_URI} [NE,R=301,L]
