Application URLs Without Trailing Slash Fail

[DarioS]

We have an index page with links such as http://shiny.maths.usyd.edu.au/CPOP that worked for the past few years. Recently, that causes a blank page to be shown with no debugging output to help troubleshoot. However, everything is fine with http://shiny.maths.usyd.edu.au/CPOP/. There was an operating system kernel update by the system administrator at around the same time as the blank screen began. Reinstalling the latest version of Shiny Server didn't help. Could Shiny Server seamlessly work for both formats? The slash-free addresses are in all of our team's published journal articles.

This issue is even more annoying for our use case as we run it through a web application firewall which handles authentication. It seems the trailing slash gets stripped out by our WAF so users need to log in, get redirected to 'Page not found' then add the slash again to get to the page.
