-  // from Netscape is possibly what is closest to the cookies used today.
-  // This spec didn't have explicit support for double quoted strings, and
-  // states that ; is not allowed as part of a value.  We had originally
-  // implement the Firefox behavior (A="B;C"; -> A="B;C";).  However, since
-  // there is no standard that makes sense, we decided to follow the behavior
-  // of IE and Safari, which is closer to the original Netscape proposal.
-  // This means that A="B;C" -> A="B;.  This also makes the code much simpler
-  // and reduces the possibility for invalid cookies, where other browsers
