The HttpKernelInterface is a lie

This talk will explore the evolution of HTTP abstractions. We will take a look at inetd at the TCP level, CGI and FCGI at the HTTP level, language level abstractions like Rack for Ruby and WSGI for Python. Finally we will arrive at the Symfony2 HttpKernelInterface. The PHP community can take many ideas from Rack. We should be building composable stacks of re-usable middlewares.
