For a while now myself and others have been looking into a way to add Let’s Encrypt support to WebCTRL. The underlying Tomcat web server and Windows platform present some unique “challenges” when you look at the Let’s Encrypt ACME client options.
ALC support reached out to me with the method below a while back and I’ve had this running on a test server for a month now and it seems to work fine. I believe there should be some interest out there for this as it is a fairly friendly and mostly free way to add HTTPS to about any HTTP web server.

Looks like a nice proxy for this.
