# When using Rack::Attack with a Rails app, developers expect the request path
# to be normalized. In particular, trailing slashes are stripped.
# (See
# https://github.com/rails/rails/blob/f8edd20/actionpack/lib/action_dispatch/journey/router/utils.rb#L5-L22
# for implementation.)
#
# Look for an ActionDispatch utility class that Rails folks would expect
# to normalize request paths. If unavailable, use a fallback class that
# doesn't normalize the path (as a non-Rails rack app developer expects).
