Based on your request, you are attempting to retrieve a value from an HTTP header sent by an external system when consuming an Anonymous Authentication service in your Pega application.

Your provided code attempts to retrieve the header value using the pxHTTPServletRequest object. However, for better clarity and accuracy, it is recommended to use the pyRequestorServlet object instead, which provides access to the current HTTP request object. Here's the revised code snippet:

javax.servlet.http.HttpServletRequest request = (javax.servlet.http.HttpServletRequest)tools.getRequestor().getRequestorPage().getObject("pyRequestorServlet"); String yourHeader = request.getHeader("iv-groups"); tools.getParameterPage().put("label", yourHeader);

It's important to ensure that the header name "iv-groups" matches the actual header name being sent from the external system.

If this solution doesn't work, there are other options you can consider. One is to add a custom HTTP header to the response from the external system and retrieve the value from that header in the Pega application. Another is to pass the value as a query parameter in the request URL.

Alternatively, you can configure the HeaderPropagationFilter in the Pega application to propagate the "iv-groups" header from the incoming request to subsequent requests in the application, including the request to the Anonymous Authentication service. To configure the HeaderPropagationFilter, add the following lines to the web.xml file:

<filter> <filter-name>HeaderPropagationFilter</filter-name> <filter-class>com.pega.pegarules.servlet.HeaderPropagationFilter</filter-class> <init-param> <param-name>propagateHeaders</param-name> <param-value>iv-groups</param-value> </init-param> </filter> <filter-mapping> <filter-name>HeaderPropagationFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

This configuration will propagate the "iv-groups" header to all requests in the Pega application. The header value can then be accessed in the Anonymous Authentication service using the pyRequestorServlet object.

Additionally, to better clarify the custom Authentication Service rule, it may be useful to mention that the rule should be associated with the Anonymous access group, and that the Java step can be added to either the "Validate" or "Post Authentication" section, depending on the specific use case. Here are the steps to create the custom Authentication Service rule:

1. Click on "New" in the "Records" explorer and select "Authentication Service" from the list of rule types.

2. Give the new rule a name and select "Anonymous" as the base class.

3. Click "Create and open" to open the rule form.

4. In the "Steps" tab, add a new Java step by clicking on "Add step" and selecting "Java" from the list of step types.

5. In the Java step, add the following code: javax.servlet.http.HttpServletRequest request = (javax.servlet.http.HttpServletRequest)tools.getRequestor().getRequestorPage().getObject("pxHTTPServletRequest"); String yourHeader = request.getHeader("iv-groups"); tools.getParameterPage().put("label", yourHeader);

6. Save the rule.

In addition to these solutions, it's worth noting that the root cause of the issue may lie in the configuration of the external system sending the HTTP header. Consultation with other Pega experts or support resources may be helpful for additional insights and guidance.
