public function getEtag(); public function setEtag($value);
ipworksedi_as2sender_get($res, 37 ); ipworksedi_as2sender_set($res, 37, $value );
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.
