How do I use tls v1.2 on older version of Cache for Windows (x86-64) 2011.1.2 (Build 701)

TLS version 1.2 is not supported on Caché for Windows versions previous to 2015.2. This is because they use older versions of the openssl library which do not have support for TLSv1.1 and 1.2. I found this previous post informative: https://community.intersystems.com/post/tls-v12-support-cach%C3%A9
