Usually we buy the host space is the most commonly used in Windows and Linux two kinds of systems, the following will be said in both cases to achieve what conditions to do 301 redirects, and how to do 301 redirect.

If you support. htaccess, how do you do 301 redirects?

First of all 2 domain names with www and no www are resolved to our host IP address, then add the following rules at the beginning of the. htaccess file:

Rewritecond%{http_host} ^adminseo.net [NC]

Rewriterule ^ (. *) $ http://www.adminseo.net/$1 [r=301,l]

2. Windows hosts typically use IIS servers that are required to install Isapi_rewrite This component (that is, usually using the most of the pseudo static environment we call it), and if so how do we support 301 redirects? Do not support us and how to deal with it?

If the Isapi_rewrite component is supported, the first 2 domain names with www and no www are resolved to the IP address of our host, and the following rules are added at the beginning of the Httpd.ini (usually called pseudo static rule file) file:

Rewritecond Host: ^adminseo\.net$

Rewriterule (. *) http\://www\.adminseo\.net$1 [r,i]

If the Isapi_rewrite component is not supported, it can only be done through IIS (suitable for your own server, or for the virtual host provider to help resolve), as follows:

First, create a new Web site under IIS, the Site directory (available from the original site folder can also create a new folder, arbitrary) only need 2 files: Default.htm and 404.htm, the new site host header binding needs to do 301 redirect URL, as shown above: Admiseo.net need to do 301 to www.adminseo.net on the new Web site's host head bound adminseo.net, new after the completion of the new Web site Right-click, select Properties, select the home directory in the property panel, as shown in the following figure, select Redirect to URL , and then enter the URL, do not forget to "resource permanent redirect" option on the hook Oh!

1, if it is a new domain name and site, no WWW domain name has not been included in the search engine, then you can use the way to forward the URL, without the domain name of the WWW to the domain name with www, in the domain name management background can be set forward, It is noteworthy that at present some of the domain name registrars have made certain restrictions on the URL forwarding.
