New Revision: 1627746
URL: http://svn.apache.org/r1627746
Log:
Merge TestCookies[Allow|Disallow]Equals now that it is no longer necessary to
use a system property to change this.
Move allowNameOnly cookies to a CookieProcessor property as this needs to be
set to allow the new equals test to work.
Fix an edge case and allow a cookie with a value that starts with = to be
treated as a name only cookie if = is not allowed in values but name only
cookies are permitted.
