Class Http64Encoder

- public class Http64Encoder
- extends sun.misc.CharacterEncoder
This class encodes characters using a variant of Base64 encoding that results
in an encoded string that doesn't need to be escaped for use in HTTP URLs.
Specifically, the following characters are remapped in this implementation:
Location Base64 Http64
-------- ------ ------
62 + -
63 / _
(pad) = $
The Base64 implementation relies on the sun.misc.*
package
included with Sun's implementation of the Java Platform; there is no
guarantee that this implementation will be used in future versions of this
class.

printable characters. Note that if the length in len is less
than three is encodes either one or two '=' signs to indicate
padding characters.
