Fix for https://support.microsoft.com/en-gb/kb/899927

	# If you're using Rails, add this file to app/middleware/microsoft_hyperlink_library_middleware.rb
	# And add the following to your config/application.rb (note the string class name):
	#
	# config.middleware.use "MicrosoftHyperlinkLibraryMiddleware"
	#
	# This will fix the awful bug described in https://support.microsoft.com/en-gb/kb/899927 where
	# links from PowerPoint or Word that require an authenticated session continually go to your
	# log in page even when a user is authenticated.
	#
	# The workaround is to rewrite any server-side HTTP redirects to client-side redirects
