Redirect 301 www.www.example.com

Question

I am using a LAMP server and I need to redirect requests, for example:

www.www.example.com to www.example.com and other options such as (wwww.example.com, etc.)

I know I can do this in .htaccess, but I don’t know the regular expression that I have to use to represent all of these features.

Or is there any other approach coming from vhosts?

Answer 1

I like:

# force www IN URL RewriteEngine on RewriteCond %{HTTP_HOST} !^www\.example\.com [NC] RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L] # END force www IN URL 

In principle, everything that cannot be redirected to www.example.com 301.d.

Answer 2

See this article for the implementation of "wildcard subdomains." You will need to implement both .htaccess and the Vhosts modification.

If you want to limit it to only "www.www", "wwww." and the other examples above, you can easily do this with some server-side code (which makes it more flexible than embedding more .htaccess). Just determine what a subdomain is and redirect to wherever you want.

Answer 3

Using name-based virtual hosts in Apache, you can do this:

 <VirtualHost *:80> ServerName example.com ServerAlias wwww.example.com www.www.example.com [space seperated list] Redirect / http://www.example.com/ </VirtualHost> 

The redirect can take a parameter to indicate the type of redirection.
