How to Use the HTTP Status Checker
Single URL Testing
- 1Enter URL: Type or paste the complete URL including protocol (http:// or https://).

- 3Configure Batch Settings: Set batch size and delay between requests to avoid rate limiting.
- 4Start Bulk Check: Monitor progress and export results to CSV when complete.
Best Practices & Tips
Testing Guidelines
- ✓Use HEAD requests for status checks to save bandwidth
- ✓Set appropriate timeouts based on expected response times
- ✓Use smaller batch sizes for servers with rate limiting
- ✓Add delays between requests to be respectful to servers
- ✓Test both HTTP and HTTPS versions of URLs
Troubleshooting
- ⓘCORS errors are normal due to browser security policies
- ⓘTimeout errors may indicate slow or unresponsive servers
- ⓘNetwork errors suggest connectivity or DNS issues
- ⓘSome servers may block automated requests
- ⓘResponse times may vary due to geographic location
Technical Information
Privacy & Security
- • All requests are processed through a CORS proxy for browser compatibility
- • No URLs or results are stored on our servers
- • All data processing happens in your browser
- • Use HEAD requests by default to minimize data transfer
Limitations
- • Subject to CORS proxy availability and rate limits
- • Response headers may be limited by CORS policies
- • Very large bulk checks may be rate-limited
- • Some enterprise firewalls may block proxy requests
