I have configured Apache to return HSTS header. When connecting to https://lab20.example.com from Google Chrome and running with developer tools I can see the following response header:
But it does not work. When I try to access the http://lab20.example.com, Chrome allows that.
Also when running from chrome:
chrome://net-internals/#hsts Query domain "lab20.example.com" I receive "Response Not found".
Could anyone explain why this happens?
