[julienvey]

Should be an option of the rest client

This bug is quite annoying.

It is strange that according to rest-client README it should automatically follow a redirect if the request is GET, but my setup doesn't seem to do it. I don't know should we just copy the "Follow redirections for all request types and not only for get and head" example from rest-client to http_utils.rb

I agree this is an important bug. I add it to the next milestone.
