Produce a copy of a string in which the characters '+', '%', '=', ';'
and control characters are replaced with "%hh". This is a gentle form
of URL encoding, attempting to cause as little distortion to the
string as possible. The characters '=' and ';' are meta characters in
cookies. By convention, they are escaped using the URL-encoding. This is
only a convention, not a standard. Often, cookies are expected to have
encoded values. We encode '=' and ';' because we must. We encode '%' and
'+' because they are meta characters in URL encoding.
Convert a cookie specification string into a JSONObject. The string
will contain a name value pair separated by '='. The name and the value
will be unescaped, possibly converting '+' and '%' sequences. The
cookie properties may follow, separated by ';', also represented as
name=value (except the secure property, which does not have a value).
The name will be stored under the key "name", and the value will be
stored under the key "value". This method does not do checking or
validation of the parameters. It only converts the cookie string into
string - The cookie specification string.
A JSONObject containing "name", "value", and possibly other
Convert a JSONObject into a cookie specification string. The JSONObject
must contain "name" and "value" members.
If the JSONObject contains "expires", "domain", "path", or "secure"
members, they will be appended to the cookie specification string.
All other members are ignored.
