#post_init ⇒ Object

This is intentionally completely overriden from the superclass’s version as it is required to re use the listeners on the parser for a second time around if an SSL address is being proxied

#receive_data(data) ⇒ Object

Deliberately overriding this from the superclass as we want to prevent everything after parsing of the data IF this is restarting
