The WebLink Component

Warning: You are browsing the documentation for Symfony 3.x, which is no longer maintained.

The WebLink component provides tools to manage the Link HTTP header needed for Web Linking when using HTTP/2 Server Push as well as Resource Hints.

Installation

        $ composer require symfony/web-link:^3.4
    

Note

If you install this component outside of a Symfony application, you must require the vendor/autoload.php file in your code to enable the class autoloading mechanism provided by Composer. Read this article for more details.
