+#### Cache and Site Data Management
+
+You can control browser cache and site data for testing, performance optimization, and privacy:
+
+```bash
+# Cache Management
+# Disable cache for current tab (useful for testing)
+cremote disable-cache [--tab="<tab-id>"] [--timeout=5]
+
+# Enable cache for current tab
+cremote enable-cache [--tab="<tab-id>"] [--timeout=5]
+
+# Clear browser cache for current tab
+cremote clear-cache [--tab="<tab-id>"] [--timeout=5]
+
+# Site Data Management
+# Clear ALL site data (cookies, storage, cache, etc.)
+cremote clear-all-site-data [--tab="<tab-id>"] [--timeout=10]
+
+# Clear only cookies
+cremote clear-cookies [--tab="<tab-id>"] [--timeout=5]

+**Use Cases:**
+- **Testing**: Disable cache to ensure fresh page loads without cached resources
+- **Performance Testing**: Clear cache to test cold load performance
+- **Debugging**: Clear cache to resolve cache-related issues
+- **Development**: Disable cache during development to see changes immediately
+- **Authentication Testing**: Clear cookies to test login/logout flows
+- **Privacy Testing**: Clear all site data to test clean state scenarios
+- **Storage Testing**: Clear web storage to test application state management

+The `--timeout` parameter specifies how many seconds to wait for the operation to complete (default: 5 seconds, use longer timeouts for comprehensive data clearing).
