I'm not correctly understanding what the index.php should look like for the kerneldispatcher setup:

If I look at the linked documentation: https://foshttpcache.readthedocs.io/en/latest/proxy-clients.html#kerneldispatcher-for-single-server-installations

The following lines:

// Tell the kernel about the cache $kernel->setHttpCache($httpCache); // Create the Symfony proxy client with KernelDispatcher $kernelDispatcher = new KernelDispatcher($kernel); $symfony = new Symfony($kernelDispatcher);

are confusing me.

Should it not be enough the following implementation:

// ... $kernel = new Kernel(...); + if (SYMFONY_ENV !== 'dev') { + $kernel = new HttpCache($kernel); + }

If I look at the symony basic index.php there is no KernelDispatcher or Symfony. Also not clear if $httpCache->handle need to be called or $kernel->handle I'm really confused if this lines are really needed.
