As part of my “Get On The App Wagon” talk at Directions EMEA 2013, I talked about hiding a NAV 2013 Application Tier Server behind an Internet Information Server.
The design is a simple Proxy that get requests from the internet, and sends them to a NAV2013 behind the IIS.
Download the ASP.NET pages here NAV Proxy – Right now the NAV URL is just hard coded inside the pages, so remember to change the URLs to match your NAV installation.
