def uri_escape(string)
  # Here, we want to do CGI.escape to encode '/', but GF (Plack?) does URI.unescape when it receives.
  # Major Difference: In URI.escape, ' ' => '%20'. In CGI.escape, ' ' => '+'.
  # Thus, we need to convert as ' ' => '+', and then, '+' => '%20' so that GF can unescape '%20' => ' '.
  # '.' => '%2E' because a/./b is recognized as a/b as URL
  CGI.escape(string).gsub('+', '%20').gsub('.', '%2E') if string
