Privileged Account User logon to the WebGUI >> Open the service to modified: From the Control Panel, select the type of service to be edited (e.g., Multi-Protocol Gateway) >> The list of available services will be displayed >> Click the name of the service to be edited (NOTE: this process is specific to a previously configured service in support of a defined use-case and addressing specific business and technical requirements).

Modify the service’s processing policy: Click the “…” button adjacent to the configured Processing Policy (in the case of a Web Service Proxy, click the “Policy” processing policy tab) >> The processing policy is displayed.

Select the rule to be edited by clicking the “Rule Name”.

Configure the Conditional Action: Drag the “Advanced” action to the desired point in the processing rule and double click it >> Select the “Conditional” action and click “Next” >> The “Configure Conditional Action” window is displayed >> A new rule is displayed, consisting of a “Match Condition” and an “Action”.

Paste the XPath statement corresponding to the positive test condition (i.e., the condition that, if met, would allow the message to be processed) into the “Math Condition” field >> In the corresponding “Action”, select “Set Variable” >> Click “Create Action” >> The “Configure Set Variable Action” window is displayed >> In the Variable Name field, paste “service/routing-url” >> In the Viable Assignment field, enter the desired target URL (e.g., (http://somehost.com:port/someURI”) >> Click “Done”.

In addition to the rule that was just configured, a new rule is displayed, consisting of a “Match Condition” and an “Action”.

Paste the XPath statement corresponding to the negative test condition (i.e., the condition that, if met, would result in the message being blocked) into the “Math Condition” field >> In the corresponding “Action”, select “Call Processing Rule” >> Click “Create Action” >> The “Configure Call Processing Rule Action” window is displayed >> From the “Processing Rule” drop-down list, select the name of the processing policy’s configured error rule >> Click “Done” >> Click “Done” >> Click “Apply Policy” >> Click “Close Window” >> Click the “Apply” button >>
