* The purpose of UrlBase64 encoding is to provide a compact encoding of binary
|

* data that is safe for use as an URL parameter. Base64 encoding does not
|
|
* produce encoded values that are safe for use in URLs, since "/" can be
|
|
* interpreted as a path delimiter; "+" is the encoded form of a space; and
|
|
* "=" is used to separate a name from the corresponding value in an URL
|
|
* parameter.
