Reproduce response behavior before changing routing code

A routing bug often crosses layers: CDN, proxy, framework, application, and browser. AnalyseSpider helps keep the captured evidence intact while you decide which layer to inspect next.

Decision rule

Use the tools to narrow the owner of a response. Do not treat a pasted capture as proof of every environment or request context.

01

Capture the response as delivered

Keep status, Location, cache fields, content type, X-Robots-Tag, and relevant HTML together. Record the exact URL and request context that produced them.

  • Relative and absolute redirect targets
  • Host and scheme changes
  • Header and HTML directive conflicts
  • Final response status and representation
02

Use unknowns as test cases

If the capture omits a request header, intermediate hop, CDN state, or authenticated variant, mark it unknown. That missing field becomes the next reproducible test rather than an excuse for a broad configuration change.

03

No network side effects

The current inspectors parse pasted input in the browser. They do not issue an unrestricted server-side request, scan ports, or crawl a target.

Networked diagnostics remain out of scope until egress controls, DNS-rebinding protection, rate limits, response caps, abuse monitoring, and ownership are reviewed.
