# There's a bug in Rack 1.1.x which is fixed in Rack 1.2, but our
# current version of Rails won't use that. So for now, monkeypatch,
# This can be dropped when we move to Rails 3.
#
# See https://github.com/sebbacon/alaveteli/issues/38 for Alaveteli
# bug report
#
# More info about the monkeypatch:
