macOS Disable save request? Doc based app xcode

[Heli0s38]

Hello! (again)

my question is simple this time.

how do i disable the request that pops up to save the "document" on close when its running?

i am making a web browser which shouldnt be needing to "save".

ive googled around and for the life of me i cant seem to find the answer that says "press big red button X"

is there a way to disable it?

is there not a way?... if not is there a bit of code i can implement to suppress it?
