Www to non www

[seoug_2005]

Hi,

Is this the correct code for redirecting www to non www version on Apache server

RewriteEngine

OnRewriteCond %{HTTP_HOST} ^www.example.com

RewriteRule (.*) http://www.example.com/$1 [R=301,L]

Thanks

RewriteEngine On

RewriteBase /

RewriteCond %{HTTP_HOST} ^www.(.*)$ [NC]

RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

Put that in your .htaccess within your root web directory (typically public_html), and you should be good.

Make sure you save your .htaccess file properly (save as "All files" and not "as text file" so the .txt doesn't get appended to it.

The $1 basically copies everything that precedes it ( http://www.example.com/ )

This is so that for each URL it rewrites you don't have to give it the above URL over and over again.

Hope this makes sense 

**'**If the matched regex contains groups in parentheses, $1..$9 in the replacement refer to the captured text in the
matching group "$1" meaning the first group, "$2" the second, and so on.'

Look i work on windows servers so i dont use htaccess, so i am no expert with htaccess, but I do know regex pretty well,

I think you have it wrong in 2 ways.

1. you are directed from non www. to www the wrong way.

Also the rewrite condition is a RegEx, it needs to be escaped

so i think you should have

RewriteCond %{HTTP_HOST} ^www.example.com

RewriteRule (.*) http://example.com/$1 [R=301,L]

This is all so much easier on windows servers

[seoug_2005]

Is this correct

RewriteEngine on

RewriteCond %{HTTP_HOST} ^example.com

RewriteRule (.*) http://www.example.com/$1 [R=301,L]

What does $1 mean ?

[SteveOllington]

You've just missed the "on" at the end of the first line and have it at the start of the 2nd I think (not sure if that matters). So,

RewriteEngine On

And then take the www off the second line. So,

RewriteCond %{HTTP_HOST} ^example.com
