What's going on when the app redirects to an absolute URL?
* Sinatra relies on Rack::MockSession which sets SERVER_NAME to
"example.org" [1] on request it makes. However, Webrat expects
it to be "www.example.com"
* In MyClassyApp, the redirect URL is made out of Rack::Request#url [2]
which uses SERVER_NAME, which is set to "example.org" by Rack::MockSession.
As a result, Webrat see it as an external redirect and don't follow it.
NOTE:
* SERVER_NAME is stricly equivalent to HTTP_HOST [3]
* This could have been fixed in Webrat::Session too. I'am not sure
that it won't affect other frameworks so I left it intact.
def request_page(url, http_method, data) #:nodoc:
h = headers
h['HTTP_REFERER'] = @current_url if @current_url
+ h['HTTP_HOST'] = 'www.example.com'
