Which property must be provided to configure external HTTP clients in Activegate?

To configure external HTTP clients in Activegate, the property that must be provided is related to user authentication, specifically the proxy user. When dealing with external HTTP clients, it's often necessary to authenticate the clients to ensure secure and authorized access to resources. Specifying a proxy user allows the Activegate to authenticate requests from the HTTP clients to backend services or APIs.

This property ensures that the Activegate can handle the communication properly by establishing a trusted relationship via authentication. Without providing a proxy user, there could be issues related to security and authorization, potentially leading to failed requests or inaccessible resources.

The other properties mentioned serve different purposes. For example, trustedstore-type might be relevant for SSL configuration but is not required to set up the basic external HTTP client functionality. MaxAgeDays could pertain to caching or token expiration but does not directly relate to the initial connection setup. DumpSupported is not a typical configuration requirement for HTTP client setup in this context.
