Comment:
Section 5.3 Origin.  "Two origins are said to be the same origin if the
following algorithm returns true: [...] If A and B have port components that
are not identical, return false."

IE8 and IE9 do not conform to this.  Per
http://msdn.microsoft.com/en-us/library/ms537505.aspx : "In Internet Explorer
8 and later, that restriction has been removed. Internet Explorer does not
consider the port to be a part of the Security Identifier (origin) used for
Same Origin Policy enforcement."

If the outlined algorithm becomes the standard that developers code by, then
it is crucial that all browsers follow this algorithm otherwise serious
security problems could arise.    If the outlined algorithm is the way forward,
please put pressure on Microsoft to patch IE8 and beyond to conform.
