Defined in:

Overview

This middleware class will detect and handle collisions with forwarded ports, whether that means raising an error or repairing them automatically.

Parameters it takes from the environment hash:

* `:port_collision_repair` - If true, it will attempt to repair
  port collisions. If false, it will raise an exception when
  there is a collision.

* `:port_collision_extra_in_use` - An array of ports that are
  considered in use.

* `:port_collision_remap` - A hash remapping certain host ports
  to other host ports.
