In all honesty, this isn't something that should be done in javascript, it should be done at the server level. The reason is that if you do it in javascript, the person will have to download the javascript, the javascript will then redirect the user, which will then send another request to the server, and the user will have to download the page, including the javascript from before, all again.

 

If it's done on the server side, the browser makes a request to the server, the server sees that the URL is wrong, and sends the user the data for the proper page. Much faster and better.

 

You can do it in an .htaccess file with the following:

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

(note: you will need to change both 'example.com' to your actual domain name)

If you can't do it through the .htaccess, then you'd be better off using a PHP redirect then.

 

Basically, anything non-javascript or HTML is a better solution.

Hi,

after some googling i have found the solution and its working great,following is the code i have used,

 

<!--

enURL = document.URL;

 

if(enURL.indexOf("www") == -1 )

{

location.href = enURL.replace("http://", "http://www.");

}

// -->
