In modern web architecture, "H5" refers directly to lightweight, responsive web pages optimized specifically for mobile browsers and in-app web views (such as WeChat, WhatsApp, or custom webview wrappers).
: Simulate up to 50,000 concurrent user sessions using tools like Apache JMeter or Locust to verify your priority routing stays stable under pressure. Step 1: Enforce Upstream Session Persistence # Nginx
Modify your Nginx or reverse proxy configuration to handle the Agent4U priority routing. Ensure the upstream block contains sticky routing flags to keep VIP sessions locked to the identical backend server block.
