How do I set "Strict Transport Security" to my site?

[Wuser1]

I would like to add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload" to Apache .htaccess file. how do I make it or is there other option?

My site already uses SSL.

Thanks for joining the Community and making your first post, @Wuser1.

Unfortunately, there isn't a way to add that as we don't provide direct access to the .htaccess file for your site.

Thank you Adam

I see, I hope we make it someday.

Is there an update to the HSTS issue?

Description

HTTP Strict Transport Security is an HTTP header that instructs clients (e.g., web browsers) to only connect to a website over encrypted HTTPS connections. Clients that respect this header will automatically upgrade all connection attempts from HTTP to HTTPS. After a client receives the HSTS header upon its first website visit, future connections to that website are protected against Man-in-the-Middle attacks that attempt to downgrade to an unencrypted HTTP connection. The browser will expire the HTTP Strict Transport Security header after the number of seconds configured in the max-age attribute.
