This seems like a reasonable useful configuration.
Could you add that property to the list displayed on
the System Properties page?
Actually, that’‘s not how the system properties really work. Normally, we create an option in the admin console to directly enable/disable a feature. That then sets a system property under the hood. In general, people shouldn’‘t need to visit the system properties page to do configuration – it’'s just there for special cases. When we do the work of refactoring TLS support, we could definitely also add some more network configuration options to the admin console at that time.
Also, is there a list
of what properties are configurable and what they do?
Unfortunately, no, there’‘s no comprehensive list at the moment. Virtually everything can be set somewhere else in the admin console, though. There are only a few items that you have to set directly. At some point, we’'d like to document all of them though.
