* https://bugzilla.mozilla.org/attachment.cgi?id=319346
*
* HTTP AUTH:
* - hostname is always "example.com:123"
* * "example.com", "http://example.com", "http://example.com:80" all
* end up as just "example.com:80"
* * Entering "example.com:80" in the URL bar isn't recognized as a
* valid URL by IE6.
* * "https://example.com" is saved as "example.com:443"
* * "https://example.com:666" is saved as "example.com:666". Thus, for
* non-standard ports we don't know the right scheme, so create both.
*
* - an empty or missing "realm" in the WWW-Authenticate reply is stored
* as just an empty string by IE6.
*
* - IE6 will store logins where one or both (!) of the username/password
* is left blank. We don't support logins without a password, so these
* logins won't be added [addLogin() will throw].
*
* - IE6 won't recognize a URL with and embedded username/password (eg
* http://user@example.com, http://user:pass@example.com), so these
* shouldn't be encountered.
*
* - Our migration code doesn't extract non-HTTP logins (eg, FTP). So
* they shouldn't be encountered here. (Verified by saving FTP logins
* in IE and then importing in Firefox.)
*
*
* FORM LOGINS:
* - hostname is "http://site.com" or "https://site.com".
* * scheme always included
* * default port not included
* - port numbers, even for non-standard posts, are never present!
* unfortunately, this means logins will only work on the default
* port, because we don't know what the original was (or even that
* it wasn't originally stored for the original port).
* - Logins are stored without a field name by IE, but we look one up
* in the migrator for the username. The password field name will
* always be empty-string.
