 2. Select **Add rule** to add a new rule. Provide the rule a name and then select **Add an Action** > **Response Header**.
 
 3. Set the Operator to **Append** to add this header as a response to all of the incoming requests to this route.
 
 4. Add the header name: *Content-Security-Policy* and define the values this header should accept, then select **Save**. In this scenario, we choose *`script-src 'self' https://apiphany.portal.azure-api.net`*.

    > Header values are limited to 640 characters.
 
 5. Once you've added all of the rules you'd like to your configuration, don't forget to go to your preferred route and associate your Rules engine configuration to the Route Rule. This step is required to enable the rule to work.

-> [!NOTE]
-> In this scenario, we did not add [match conditions](front-door-rules-engine-match-conditions.md) to the rule. All incoming requests that match the path defined in the Route Rule will have this rule applied. If you would like it to only apply to a subset of those requests, be sure to add your specific **match conditions** to this rule.
