Redirect Checker

Trace HTTP and client-side redirects, then classify what each hop is actually doing - HTTPS upgrade, WWW or apex normalization, path rewrite, trailing slash cleanup, index-file cleanup, port normalization, query changes, fragment preservation or loss, signed-link and login parameter safety, redirect-target exposure, cookie handoff, session-cookie scope, cacheability, HSTS transport hardening, and whether the chain stacks avoidable canonicalization hops.
