Data list lookup
The Data list lookup policy item registered with the Policy system, allows you to have the policy check to see if the value of a piece of event data matches a value on a global data list that you have previously configured in the Data system.
A common use for the Data list lookup policy item is when you want to have the policy check whether the URL or site in a clients Internet request is allowed to be requested. You could create a global data list of allowed/banned URLs or sites in the Data system that the client is not permitted/not permitted to request.
To use the Data list lookup policy item:
(Please refer to the Policy system help for more information on creating policies)
- Select or create a policy to open a policy editor.
- In the Items section of the policy editor toolbox, select the Data list lookup item and drag it on to the worksheet. This will automatically open the Data list lookup properties.
- To the right of the Check that the value of field select the Insert symbol button
to open up the Symbol browser so you can choose what data value will be checked against the list.
- Select the event data that you wish to check the value of against the Data list. (In this example the Request.URL method that returns the requested URL is selected). Once you have selected a piece of event data click OK to return to the Data list lookup properties.
- From the Is contained in drop down menu, select the particular global data list that the selected event data value will be checked against. (In this example a Data list called Blocked URLs has previously been created in the Data system).
- Click OK to finish editing the Data list lookup item and return to the worksheet.
- The Data list lookup policy item will now blink, allowing you to give it a meaningful name so you can identify it easily in the policy evaluation flow.
