Etag Property
The Etag of the file being sent.
Syntax
public var etag: String {
get {...}
set {...} }
Default Value
""
Remarks
This specifies the Etag for the file. This value should be set to an empty string the first time a file is sent using the Restart command. The class will generate a unique Etag based on the processed contents of the file and set this property when sending begins.
If a file is interrupted, this value must be set when Restart is called to resume transfer of the already processed file.
