408
Request Timeout
⚠️ Client Error
Low Risk
📖 What Is HTTP 408?
The server timed out waiting for the request. The client did not produce a request within the time the server was prepared to wait.
🛡️ Security Implications
Slowloris and slow POST attacks exploit this by sending requests very slowly to exhaust server connections.
🔍 Common Causes
Slow network connection, client-side processing delay, large file upload on slow connection, or keepalive timeout.
🔧 How to Fix
Check network connectivity. Increase timeout values if needed. Implement connection-level timeouts to prevent slowloris attacks.
🖥️ How to Check
curl -I -o /dev/null -w "%{http_code}" https://example.com
