Server Push/preloading?

If the method just adds Link header, I don't think it is worth to add a new method to Response class.

Code:

Link: </css/style.css>; rel="preload"; as="style"

1. We can use <link> tag in HTML like

Code:

<link rel="preload" as="script" href="critical.js">

2. We have already a method to add headers. https://codeigniter4.github.io/CodeIgnit...ng-headers
