SessionDefibrillator - Keep Web Sessions Alive

⚠️ SECURITY WARNING
Keeping sessions alive creates security risks. Your session remains active even when away from your computer. ALWAYS lock your computer when stepping away.

USE AT YOUR OWN RISK. You are solely responsible for any consequences. The developers accept NO liability for damage, data loss, security breaches, or violations of website terms of service.

OVERVIEW
Automatically pings configured APIs at regular intervals to keep web sessions active and prevent automatic logouts.

FEATURES
• Configurable API endpoint pinging
• Automatic session monitoring on specified websites
• Kill timer that auto-stops after configured duration (security feature)
• Click detection resets the kill timer automatically
• Easy settings management via options page
• Works with any GET endpoint

CONFIGURATION
1. Click extension icon → "Open Settings"
2. Enter Host Wildcard (e.g., https://app.yourcompany.com/*)
3. Enter API URL (your keep-alive endpoint)
4. Set Session Duration (default: 120 minutes)
5. Set Ping Interval (default: 2 minutes)
6. Click "Save and Start Pinging"
7. Grant permissions when prompted

HOW IT WORKS
• Extension only activates on pages matching your Host Wildcard
• Automatically starts pinging when you visit matching pages
• Pings API at configured intervals
• Kill timer resets every time you click on the page
• Stops automatically after Session Duration expires (for security)
• Red badge (!) indicates pinging has stopped

RESTARTING AFTER TIMEOUT

Method 2: Refresh the webpage
Method 3: Navigate to any matching page

TROUBLESHOOTING
• Not starting? Check permissions and verify Host Wildcard matches current page URL
• Badge shows "!"? Pinging stopped - restart using methods above
• CORS errors? Ensure API allows cross-origin requests from browser extensions
