.htaccess help with 301 redirect

htaccess 301 redirect

[kk4uga]

I'm having an issue where Google is picking up some of my pages as ns1.domain.com instead of www.domain.com. I have a htaccess file (see below), but the ns1 search results do not forward to www. Any advice?

Options +FollowSymLinks
RewriteEngine on 
RewriteCond %{HTTP_HOST} ^domain.com [NC] 
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,NC]

Your code redirects example.com (with or without a port number) to www.example.com, and does nothing for ns1.example.com requests.

Correct.

How can I alter the code to redirect example.com AND ns1.example.com to www.example.com?

Thanks!

[g1smd]

To also redirect ns1 you could use:

RewriteCond %{HTTP_HOST} ^(ns1\.)?example\.com [NC]

What about www.ns1.example.com too? The new code does not redirect that.

If you want to redirect anything that is not exactly www.example.com then this is useful:

RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$

The code above is my original code. I was looking for how to edit that to include ns1.

Someone else helped me out. Here is the result:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.domain\.com [NC]
RewriteRule (.*) [domain.com...] [R=301,L]

Now the ns1 redirects to www.

The latest code will not redirect www.example.com:80 requests with a port number.

Additionally, do remember to escape all literal periods in patterns.

"The latest code will not redirect www.example.com:80 requests with a port number."

Do you have a fix? I don't know how to code that.

Already posted above:

RewriteCond %{HTTP_HOST} !^(www\.example\.com)?$

Great, thanks!

Take the [NC] off your latest RewriteCond. You *do* want to redirect if the case is incorrect.
