HTTP Headers

Servers can send HTTP headers to provide the client with additional metadata around the response. Besides sending the content that the client requested, servers are then allowed to specify how a particular resource should be read, cached or secured.
They have been implemented by browsers in order to make it harder for attackers to take advantage of vulnerabilities.

HSTS

HTTP Strict Transport Security.
A simple Strict-Transport-Security: max-age=3600 will tell the browser that for the next hour (3600 seconds) it should not interact with the applications with insecure protocols.

Installation on Linux

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
