public string TargetID { get; set; }
A System.String to absolutely identify the logical target that is being accessed, including any discretionary trans-coding performed by the server.
This field may be used to supply a unique ID string, which was generated by the server in a previous response. The TargetID uniquely identifies the logical target that is being requested at the server level.
Don't depend on the Target field to identify the image, since the same Target value will exists for requests with different ImageReturnTypes or different trans-coding.
If this field is "0", the logical target is specified through the use of the Target, SubTarget and JPIP URL path component, and the client is explicitly requesting that the server inform it of the assigned target-ID, if there is one.
