A tiny lib for managing cookies

Furnace.js

;(function(){
  // Cookie management
  window.Furnace = {
    cookie: function(name) {
      function splitCookie() {
        if (document.cookie.length == 0) {
          return null;
        }

        var start = document.cookie.indexOf(name + "=");
        if (start == -1) {
          return null;
        }

        var start = start + name.length + 1;
        var end = document.cookie.indexOf(";", start);
        if (end == -1) {
          end = document.cookie.length;
        }

        return unescape(document.cookie.substring(start, end));
      }

      return {
        name: name,
        bake: function(value) {
          document.cookie = this.name + "=" + value + "; path=/";
        },
        bite: function() {
          return splitCookie();
        },
        burn: function() {
          return this.bake(';expires=Thu, 01 Jan 1970 00:00:01 GMT');
        },
        eat: function() {
          var result = this.bite();
          this.burn();
          return result;
        }
      };
