2.9 Summary
In this lab, you learned:
● That there are three service processing phases that occur each time a message arrives.
The client-side processing performs all protocol related processing as well as shielding
against a variety of malicious attacks. The service processing phase contains all of the
specific rules and actions that you define. The server-side processing phase is where any
backside protocol tasks are performed before the message is forwarded to the intended
destination.
● WebSphere DataPower configurations are built using a pure object-oriented design. Every
configuration object, such as a SSL Proxy Profile or a Processing Policy, can be reused.
● How to configure a Multi-Protocol Gateway service, along with an HTTP Front Side
protocol handler, and a Processing Policy.
● A Processing Policy contains a set of Processing Rules; each rule begins with a Match
Action that is evaluated to determine whether the rule should be executed. Each
processing rule contains a list of processing actions that are executed against the
message.
● Match rules can match on various aspects of a message, including the URL, HTTP
headers, error codes, or an XPath that inspects the XML payload of a message.
● Clicking the Save Config link in the top navigation area will save your running
configuration (for your domain) to the flash memory. The running configuration and the
saved configuration are independent.
● How to add a schema validate action to the processing rule by dragging it from the action
palette onto the processing rule. WebSphere DataPower appliances can perform schema
validation against messages at near wire-speed, adding minimal latency to the overall
transaction time.
● SOAP requests and responses are automatically checked against a SOAP schema,
assuring that the SOAP envelope is well-formed and correct.
● Request and response XML documents are checked to assure they are well-formed.
Malformed XML is rejected which assures backend applications receive only well-formed
XML.
● Custom Filters can be used for content-based message filtering and SQL injection threat
protection.
● How to transform an XML document using a Transform action.
● XSD and XSL stylesheets are compiled and cached.
