Testing for Session Timeout
Session timeout controls how long a session remains valid after periods of inactivity or absolute time limits. Improper timeout configuration can leave sessions vulnerable to hijacking if users don't explicitly logout, especially on shared computers or public networks.

# Wait for timeout (adjust based on expected timeout)
echo "Waiting for idle timeout..."
for i in {1..60}; do
sleep 60 # Wait 1 minute
