Remove folder/application names from URLs

If your website’s address is this:

http://testsite.com/testapp/default.htm 

and you want your users to see the URL below in browser address bar (The name “testapp” is stripped out)

http://testsite.com/default.htm 

you can use the URL Rewrite Inbound rule below for removing the folder name from the FQDN:

<rewrite>
      <rules>
           <rule name="Remove testapp" stopProcessing="true">
                <match url=".*(testapp)(.+)" />
                <action type="Redirect" url=http://testsite.com{R:2} appendQueryString="false" />
           </rule>
      </rules>
</rewrite>
