Hi, I want to host my blog (that is a static blog) in Fast.io , but unfortunately, there is no way to set up Response Header until now. Please add an ability for setting up Response Header on Fast.io , because I want to secure my blog using my existing Response Headers (like Content-Security-Policy, Referrer-Policy, HSTS, X-XSS-Protection, etc) and Controlling Caches with Cache-Control Header. Also, please add an ability to set up Response Headers for Any Specific File and/or File Extension in my site too. Just like how to adding Response Headers in Netlify. Thank You ^_^
