C H A P T E R 1 Benefits of the SA8250
5
Intelligent session
recovery for secure
transactions
The SA8250 provides Intelligent Session Recovery technology for
secure transactions. By monitoring content within the response
sent back by the server, Intelligent Session Recovery detects
HTTP 400, 500, or 600 series errors, transparently rolls back the
session, and redirects the transaction to another server until the
request is fulfilled.
Response-time base
prioritized service for
secure transactions
The SA8250 enables system administrators to implement varying
classes of service, assign priority levels, and set target response
times for secure transactions. The SA8250 continually measures
the response times of each class of service group and assigns
incoming requests to the server that can fulfill those requests
within the predefined response time. If the response time exceeds
the predefined threshold, requests designated as high priority
receive preference over those of lower priority. The SA8250
offers predictable performance for high-priority secure requests.
