how does request.host get set? Is there a way to manually set the
value in request.host?
I have several application servers running rails, each has its own
internal address in the request.host, so when calling redirect_to or
url_for function, it uses the internal address which is not accessible
to the user.
what I want is to set request.host to return mysite.com, no matter
which application server it’s running on.
