301 Redirect Non WWW to WWW Using Web.config in ASP.Net


Whenever we host a domain on server, we are able to access the webpage from http://www.mydomain.com as well as http://domain.com. For SEO purposes, this is not good as Google and other search engines penalises the website as duplicate content. To resolve this, we can redirect the non-www domain to www domain.  In this post, we will see how can we do a “301 Redirect of a non WWW domain to WWW domain using web.config file in ASP.Net”.

To redirect mydomain.com to www.mydomain.com, edit your web.config file and add the below segment under the <system.webserver> section. Ensure you modify the words “mydomain.com” with your appropriate domain name.
