- * Function    :  cookie_encode
- *
- * Description :  Encodes a string so it can be used in a cookie.
- *                Replaces " ", ",", and ";" with the appropriate
- *                codes.
- *
- * Parameters  :
- *          1  :  s = String to encode.  Null-terminated.
- *
- * Returns     :  Encoded string, newly allocated on the heap. 
- *                Caller is responsible for freeing it with free().
- *                If s is NULL, or on out-of memory, returns NULL.
