/**
* Handler that looks for a binary data that exists in the HTTP payload either as a header or a cookie based on configuration.
*
Configuration:
System Properties:
- binary.http.header: http header name. Can be a comma
* separated set of names
- binary.http.cookie: http cookie name
- binary.http.encodingType: attribute value of the
* EncodingType attribute
- binary.http.valueType: attribute value of the ValueType attribute
* - binary.http.valueType.namespace: namespace for the ValueType attribute
- binary.http.valueType.prefix: namespace for
* the ValueType attribute
- binary.http.cleanToken: true or false dependending on whether the binary token has to be
* cleaned
Setters: Please see the see also section.
