**Symfony version(s) affected**: 5.2.* **Description** Symfony profiler does not work with x-forwarded-prefix header. `An exception has been thrown during the rendering of a template ("No route found for "GET /prefix/_profiler/search_bar""). ` Reason: The url generated by Twig RoutingExtension contains baseUrl and the `render` function can't match this url. [Profiler code ref](https://github.com/symfony/web-profiler-bundle/blob/c97712849f4f3e4ea0a1be7ff38fcefadaa55c47/Resources/views/Profiler/layout.html.twig#L111) **How to reproduce** 1. Proxy requests from /prefix/_profiler to /_profiler and set x-forwarded-prefix=/prefix 2. Open /prefix/_profiler **Possible Solution** Maybe way to generate internal url or reference. **Additional context** #37734
