note 420 deleted from function.setcookie by rasmus

Not sure if this is setcookie's output, or Netscape's reception of it, but if the cookie _name_ contains a character such as "/" it goes through literally, whereas if the cookie _value_ contains a "/", it gets url-encoded - which means when you fetch it back, if you don't decode it, it won't match what your program's looking for (in my case, a module other than PHP is checking the cookie). IMHO, would be more useful if it skipped encoding the cookie value, just as with the name.
