This section describes the trace collection points and the trace information that can be collected during request processing for creating an HTTP session.
The following table describes the event IDs, trace collection points, and PRF trace collection levels.
Table 8-26 Details of the trace collection points during request processing for creating an HTTP session (EADs session failover functionality)
