Implementing HSTS on F5 LTM 12.1.2 HF2 without using iRules

I read somewhere in article that beginning in v12, its available in the HTTP profile setting itself. You need not go with the Irule, but rather get this done through the HTTP profile itself.

Edit: Please follow the below article.

Note: The HTTP Strict Transport Security (HSTS) settings are only available in BIG-IP 12.0.0 and later. The Preload option is only available starting in BIG-IP 13.0.0 or later.
