Non WWW to WWW redirect with HTACCESS

It really doesn’t matter if you use www.yoursite.com or yoursite.com. I prefer non WWW version thats why Tech Stream uses a no www one, you can choose any depending on your views. Having 2 versions same time can cause problems. You can overcome this by forcing a version with 301 redirect from other version.

If you are starting up you can choose any may be toss a coin to find which version to use. If your website is been online for a while, I recommend you to do some analysis In different search engine and find out which version is widely used and make it permanent.

IF you don’t have access to .HTACCESS you can use httpd.con, most free web host don’t provide access to HTACCESS

  ServerName www.example.com
  Redirect 301 / http://example.com/

Many popular scripts, particular content management systems (CMS’s) edit the .htaccess file and add their own redirection so you may not have to add any of the code noted above. Adding these again can lead to 500 errors or improper redirection

Microsoft IIS Web Server

You need to add the code given below to a file that is included on all the pages, or directly on top of each file

If InStr(LCase(Request.ServerVariables("SERVER_NAME")),"www") = 0 Then
    Response.Status="301 Moved Permanently"
    Response.AddHeader "Location", "http://www.domain.com"
End If                  
                  

Note: these instructions require administrative access to IIS. If you do not have this access (e.g., if you have a shared hosting account on a Windows server), you should use one of the server-side scripting methods such as ASP or PHP given further below.
