## What it is
A Symfony component that manages links between resources via the Link HTTP header, implementing PSR-13, RFC 8288, RFC 9264 (Linkset), and RFC 9652 (Link-Template). It helps advise clients to preload, prefetch, dns-prefetch, and prerender assets, including 103 Early Hints support.

## Use cases
- preload css and javascript assets via Link HTTP headers
- send 103 Early Hints responses to speed up page loads
- add resource hints like dns-prefetch and prerender to responses
- serialize and parse Link headers per RFC 8288
- implement HTTP/2 server push for critical assets
- generate linkset documents in JSON or XML formats

## When to choose
- you run a PHP/Symfony web app and want to optimize asset loading with preloading and Early Hints
- you need standards-compliant Link header management (PSR-13, RFC 8288) in PHP
- you want to reduce perceived latency by hinting browsers to fetch resources early

## When to avoid
- your project is not PHP-based
- you only need frontend asset bundling rather than HTTP link management
- your server stack does not support Early Hints or HTTP/2 push and you don't need resource hints
