Problems Using Net::HTTP

Hope someone can follow this…

I have an action in a controller which attempts to use
Net::HTTP.get_response() to get pages over http so it can write them to
disk.

If I do this:
response =
Net::HTTP.get_response(URI.parse(“http://localhost:3000/index.html”))
It fails the error shown at the bottom of this post

But if I replace localhost with the name of our staging server (which is
on a different machine) it succeeds:
response =
Net::HTTP.get_response(URI.parse(“http://staging:3000/index.html”))

Both http://localhost:3000/index.html and
http://stageing:3000/index.html pull up identical pages when invoked in
a browser.

Should I be able to use
Net::HTTP.get_response(URI.parse(“http://localhost:3000/index.html”)) in
an action which itself is being invoked on localhost?

Incidentally if I try to run
response =
Net::HTTP.get_response(URI.parse(“http://staging:3000/index.html”)) on
the staging server itself, I run into the same error.
