Is there any way to completely override some / all of the headers that
rails outputs by default?
I would use response.headers["Set-Cookie"], etc, but as we all know,
this doesn't work a lot of the time for headers which rails sets
The reason I'm asking is I'm a HTTP proxy and in order to pass the
headers (content-type, set-cookie), from the requested page from the
proxy to the client, I need complete control over them.
