Symfony integrated HttpCache reverse proxy cannot serve cached responses

[Aleksa1996]

Booting Kernel happens here, before request handling:

roadrunner-bundle/src/Runtime/Runner.php

Line 21 in ed13b63

$this->kernel->boot();

So that booting is preventing this line to trigger HttpCache reverse proxy:
https://github.com/symfony/http-kernel/blob/1352be19da94ca65d54d20f977b85cee1b397f35/Kernel.php#L172

My suggestion would be to edit this:

roadrunner-bundle/config/services.php

Line 92 in ed13b63

$services->set(KernelHandler::class)

replace:

$services->set(KernelHandler::class)
        ->args([
            service('kernel'),
        ]);

with something like this:

$services->set(KernelHandler::class)
        ->args([
            service('http_cache'),
        ]);

Also we maybe need to check if http_cache is enabled in framework.yaml ?

As im not expert in this, are there any better suggestions how to solve it ? :)

Thanks!
