www. & non-www. (fixing robots.text)

When I entered my main url (with www.), it gets redirected to a url (without www.). What happened to my www.?

On some of my blog posts, such as this.

When I clicked on my affiliate link, (which I used adtrackz to cloak), the www. also disappears!

What happened? Is there a problem with my robots.text or .htaccess?

Did I place my robots text in the wrong folder? I put in in the main folder & the /blog folder.

Did I mess up the file permissions of my robots text or .htaccess?

I would like redirect all the non-www. to www., how do I do that?

Please help, thank you so much.

 

This is a .htaccess issue.

To achieve what you want to do, place the following in your .htaccess.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^yourdomain\.com
RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [R=permanent,L]

 

Thanks.

Do I place this .htaccess file in the main folder or the /blog folder or both?

 

Are you using wordpress? If yes, get the Permalink Redirect plugin, will fix all the problems.

 

Thanks, I just did that few hours ago. Works fine now.

 

it's better to make a 301 redirect with the code which is given above.

dont waste your time with robots.txt
