def path_to_regexp(path)
  # Since we want to be compatible with Ruby 1.8.7, we unfortunately can't use named captures like this:
  # Regexp.compile('^'+path.gsub(/\)/, ')?').gsub(/\//, '\/').gsub(/\./, '\.').gsub(/:(\w+)/, '(?<\\1>.+)')+'$')
  Regexp.compile('^'+path.gsub(/\)/, ')?').gsub(/\//, '\/').gsub(/\./, '\.').gsub(/:(\w+)/, '(.+)')+'$')
