url-rewriting

I have created a URL shortening which converts https://www.moneycontrol.com/news/india/karnataka-election-results-2018-live-updates-missing-mlas-raise-concerns-in-congress-jds-camp-2568569.html

into http://localhost:9909/vrUD4r


now when i hit url http://localhost:9909/vrUD4r it goes to error page!

how can i transfer/redirect http://localhost:9909/vrUD4r to http://localhost:9909/default.aspx?vrUD4r

note that value after http://localhost:9909/ can be any 6 character alphaneumeric! i.e. it can be http://localhost:9909/vrUD4r http://localhost:9909/abCD4E OR http://localhost:9909/ab342D for the different shortened urls.

i manage to shorten the long url, but how can i redirect to original url when i enter short url. i.e. if i enter http://localhost:9909/vrUD4r it must redirect me to original url : https://www.moneycontrol.com/news/india/karnataka-election-results-2018-live-updates-missing-mlas-raise-concerns-in-congress-jds-camp-2568569.html

What I have tried:

I have added default page when i hit http://localhost:9909 it goes to http://localhost:9909/default.aspx
as follows :

<defaultDocument>
   <files>
     <add value="shrtn.aspx" />
   </files>
 </defaultDocument>

also i have tried adding rewrite rule in web.config as follows :

<rewrite>
  <rules>
    <rule name="redirectRule" stopProcessing="true">
      <match url="^/*$" />
      <action type="Redirect" url="/shrtn.aspx/{R:0}" redirectType="Found"/>
    </rule>
  </rules>
</rewrite>
