How to add HSTS header in Cockpit

[aziddam]

I'm trying to include the HSTS headers in cockpit but I cant get it to work. Any recommendations on how to get this done?

This is what I have in my cockpit.conf file
[WebService]
Headers = Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

[jelly]

Cockpit-ws has no Headers configuration option see the configuration docs. So my best advice is to setup a reverse proxy.
