HTTP Request filter module

[forum_id]

Thank you. I am new to nginx, so spare me if I talk anything nonsense. I
want through link you provided, and then went through code as well. I
couldn't understand few things here
1) Can we override nginx core's directive?
2) Since that post action is been used in multiple place, how far it
safe to over write it?

Thank you once again.
