Amazon AppStream Opaque Data Specification

Opaque data sent from the entitlement service is stored in the AppStream_OpaqueData.xml file located in the C:\Users\Public\AppStream folder of the streaming application. The entitlement service generates the XML file.

This XML file uses the following format:

<AppStream> <Timestamp>yyyy-mm-dd.hh:mm:ss</Timestamp> <OpaqueData> <![CDATA[OpaqueData]]> </OpaqueData> </AppStream>

Note the following:

  • Amazon AppStream generates this XML file and then sends the file to the streaming application when a client application connects to the streaming application.

  • If your streaming application relies on this file, make sure that the file exists before executing commands that require this file.

  • The timestamp indicates when Amazon AppStream creates the file on the streaming application.

  • The OpaqueData data block cannot contain two right square brackets (]]).
