How to pass symfony response through some filter, process output?

Question

symfony

Greetings!
Everything that symfony outputs to the browser must be passed through some kind of processing. For example, replace external links with away?to=... and more.
How to do this with regular symfony or twig tools or in some other way, it is desirable that the result be cached.

Through events. Intercept the response event, change what you need, return a new Response object
