How to point different URL of same website to single domain name in ASP.NET

If you are implementing Google analytics, Google treats http://www.example.com and http://example.com as different website and give different analytics reports. But in original both sites are same.

Now your client demanding that both URL http://www.example.com and http://example.com should redirect to single URL as http://www.example.com

How to solve this?

You must have URL Rewrite module in IIS for this. If you have not then download and install from http://www.iis.net/downloads/microsoft/url-rewrite

Now make entries in web.config between <system.webServer> … </system.webServer> tag by specifying old URL lists mapping with new single URL. Finally your config file entry looks like

<rewrite>

  <rules>

      <rule name="CanonicalHostNameRule1">

          <match url="(.*)" />

          <conditions>

              <add input="{HTTP_HOST}" pattern="^www\.example\.com$" negate="true" />

          </conditions>

          <action type="Redirect" url="http://www.example.com/{R:1}" />

      </rule>

  </rules>

</rewrite>  

You can do all these activities from IIS as well and IIS will make entry in web.config for you.
