Reverse Proxy for Tableau Server

I'm trying to establish a reverse proxy for tableau server through IIS. To explain it in short, clients will be accessing http://localhost/tableau which will in turn do a reverse proxy to http://tableau.abc.local:8000/

I am using URL rewrite modules in IIS server to enable this. But using the URL rewrite rule, I am not able to modify the URLs getting generated in the JavaScript function block of the HTML response. Has anyone used IIS to reverse proxy for Tableau server? If so, would be great if you can help me figure out the problem. 

Below is the web.config file:
