Are you interested that I add a new P.R. to support port in access_control?
Currently if we would like to use access_control to redirect at, for example, localhost:8080, it is not possible.
So for improve this possibility I suggest to add a new key named port.

Because Request::getHost() only retrieve the host without port.

And this is what is used to compare at this place

Or we could go even further by adding a new key named redirect_to and if all is respected, we could use the key redirect the user to the value of this key.

What do think of that?
