Auto Hash Transaction Discovery

The Auto Hash Transaction Discovery data protocol uses the hash code of the data to identify a message. The hash code changes with even a slight change in the data, which effectively makes all requests unique. This data protocol is useful if you run the same small set of requests against the service.

The Auto Hash Transaction Discovery data protocol has a simple purpose. As it is given requests to handle, the standard Java hash code function is applied to the text version of the request body. The resulting hash code value is then added as a new argument in the request named lisa.vse.auto.hashDiscovery.

This ability can be helpful, especially in virtualizing messaging, for creating a reasonably unique value to use for identifying conversations.

Because this protocol requires no configuration information, it does not present a window in the recording wizard.
