Unsolicited / well-known requests

Paths a user agent fetched on its own that ua-tracer never links to: robots.txt, sitemap.xml, /.well-known/*, llms.txt, the root favicon, and similar. Reveals what an agent probes on its own initiative.

Requests (0 shown)

The Related trace column links a probe to a homepage trace from the same user agent and IP within 30 minutes (the same crawler that fetched a well-known file usually also loaded /). The offset shows how long before/after the probe that trace was minted.

No unsolicited probe requests match the current filter.
