Diagnostic report for Impark Reef app displaying outdated parking rates. Focus: API caching, TLS/SSL, DNS issues. Safe & professional guidance for commercial kiosks.
Check the server-side configuration to confirm the accurate rate schedule.
Investigate DNS caching and propagation delays.
Determine the frequency of automated rate updates.
The Reef application relies on secure API calls (HTTPS) to retrieve parking rate information from a backend server. The server transmits JSON data containing rate schedules. Potential points of failure include: TLS/SSL handshake failures, API endpoint errors (e.g., 500 Internal Server Error, 404 Not Found), DNS resolution failures, or caching of outdated rate data by the application or intermediate servers (CDN). The data transmission relies on JSON parity, so malformed JSON would cause a system failure.
The kiosk is located in a public, unattended environment. Avoid modifications or actions that could compromise the system's security or functionality. Ensure hands are dry when interacting with the device in an outdoor environment to prevent electrical hazards. Report any vandalism or damage to the device immediately to the appropriate authorities.
Implement a robust cache invalidation strategy on the server-side to ensure timely updates to the rate schedule. Monitor API response times and error rates to proactively identify and address potential issues. Ensure the application automatically refreshes the rate schedule at regular intervals (e.g., daily) and after any rate changes are implemented on the server.
Monitor the API response headers for cache control directives (e.g., Cache-Control: max-age, Expires). These headers indicate how long the application or intermediate servers should cache the rate information. A low max-age value can help reduce the likelihood of outdated rate schedules being displayed. Also, check for a 'Pragma: no-cache' directive which can force a refresh.
