What is the role of a layer in a ProxySG configuration?

The role of a layer in a ProxySG configuration is to organize rules and actions. In the context of a proxy server, layers serve as a structural component that helps to create a clear hierarchy for managing different policies and configurations. Each layer can contain specific rules and actions that apply under certain conditions, allowing for easier management and modification of proxy policies.

By logically structuring these rules within layers, administrators can ensure that related functions and policies are grouped together, facilitating better organization and ease of troubleshooting. This hierarchical organization allows for more granular control over traffic and user requests, making it possible to implement complex policy decisions efficiently.

This structured approach contrasts with the other options, which focus on distinct functionalities that layers do not primarily serve. For instance, while logs are indeed an important aspect of ProxySG, they are stored separately and are not organized within the layer structure. User roles, which define what access privileges users have, are typically managed in a different system. Connection management also involves other components of the proxy that handle traffic flow and performance, rather than being defined by the layer organization.
