Use htaccess to normalize the configuration of URLs _linux

This article addresses two issues:

The first is: if the visit of the Web site is not added to the WWW will automatically add www

Second: If the access URL is the alias point, then automatically converted to the primary domain name

The first problem-solving method:

Rewriteengine on
Rewritecond%{http_host} ^jb51.net [NC]
Rewriterule ^ (. *) $ http://www.jb51.net/$1 [r=301,l]

The second problem is solved:

Rewriteengine on
Rewritecond%{http_host} ^jb51.net$ [OR]
Rewritecond%{http_host} ^www.jb51.net$
Rewriterule ^ (. *) $ http://www.jb51.net/$1 [r=301,l]

As above, I was converting all the domain names from jb51.net and www.jb51.net to Jb51.net
