HTTP Strict-Transport-Security (HSTS) is an HTTP header that tells a browser to only communicate with a website using a secure connection (HTTPS). This helps to protect against man-in-the-middle attacks by ensuring that the connection between the user's browser and the website is encrypted.
HSTS is an important security feature that can help to protect against a variety of attacks, and it is highly recommended that you implement it on your website if you are using HTTPS.
