Technical Details
The Bookmark Health Checker validates batches of URLs by initiating asynchronous HTTP HEAD/GET requests:
- Status Code Categorization: Groups links into
200 OK(Healthy),301/302(Redirected),404(Not Found), and5xx(Server Error). - SSL/TLS Validation: Flags expired certificates, hostname mismatches, and mixed-content insecure links (
http://). - Response Time Benchmarking: Measures round-trip latency to identify slow or degraded hosting servers.
- Export Reports: Filter dead links and download verified clean URL lists.
