How to 301 Redirect permannent By SEO POINT

According to SEO POINT How to redirect URL

301 non-www to www

RewriteEngine On
ErrorDocument 401 http://wwww.example.com/
ErrorDocument 404 http://www.example.com/
RewriteRule ^index.htm$ http://www.example.com/ [R=301,L]
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]

You have only to put 'RewriteEngine On' once at the top of your .htaccess file.

This symbol ^(*.)$' says that we'll take anything that comes after http://example.com and append it to the end of 'http://www.example.com' (that is the '$1' part) and redirect to that URL. For more grit on how this works checkout a good regular expressions resource or two.



301 www to non-www

Finally www 301 redirect to non-www version would look like:


RewriteCond %{HTTP_HOST} ^www.example.com [NC]
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]
