Code Review Request: 7169142: CookieHandler does not work with localhost

[Kurchi Hazra]

Hi,

     The problem that this bug points out is that when a cookie is from 
a localhost and
no domain is set, our implementation sets the default domain of the 
cookie to its uri.getHost() [1], (which is
localhost here), and since the domain now does not contain .local, the 
cookie gets rejected.

Section 3.3.1 of RFC 2965[2] mentions that a domain should default to 
"effective request-host", where the
effective host name is derived from a host name containing no dots by 
adding the string ".local" to it.
This patch proposes adding a .local to hosts not containing any dots.
