Explanation
The authentication cache (A) and DNS cache (D) are the two primary caches cleared when troubleshooting request-processing issues on the Cisco WSA. The authentication cache stores the results of user authentication lookups; if stale, users may be blocked or improperly identified. The DNS cache stores hostname-to-IP resolutions; stale DNS entries can cause requests to be routed incorrectly or fail entirely. Clearing both ensures the WSA re-authenticates users against the directory and re-resolves hostnames through DNS. The application cache (B) and logging cache (C) are not standard WSA troubleshooting targets, and while an HTTP cache (E) exists, it is not a primary troubleshooting step for request-processing issues.
