You can configure replay detection in Java components (which includes the CLC, UFS, OSG,
Walrus, and SC) to allow replays of the same message for a set time period.
Important: To protect against replay attacks, the Java components cache messages only
for 15 minutes. So it’s important that any client tools used to interact with the
components have the Expires element set to a value less than 15 minutes from the
current time. This is usually not an issue with standard tools, such as euca2ools
and Amazon EC2 API Tools.
