HTTPS Redirect Checker — HTTP to TLS Redirect Chain
Trace redirect-chain hops — confirm http:// upgrades to https:// and read final URL with crossDomain flag
How to Use This Tool
- Enter http:// or https:// URL — bare hostnames get https:// prefix when scheme omitted.
- URL passes SSRF-safe validation before server-side fetch.
- Each hop uses redirect manual mode — records status and Location header.
- Relative Location resolves against prior hop URL automatically.
- Chain stops at non-3xx response or twelve hop safety cap.
- Review redirectCount, finalUrl, crossDomain, and ordered chain array.
About This Tool
HSTS preload and browser defaults assume HTTP URLs redirect to HTTPS — but misconfigured virtual hosts, missing apex rules, and infinite www loops leave plaintext entry points. VSPIC HTTPS redirect checker calls the redirect-chain action with your URL, following up to twelve manual HTTP 3xx hops without executing JavaScript, recording each step status, url, and location, plus startUrl, finalUrl, redirectCount, crossDomain boolean, summary, and note about manual redirect limits.
Paste http://example.com to verify upgrade to https://, or https entry points to audit canonicalization chains. crossDomain true when final hostname differs from start — expected during apex consolidation, suspicious when redirecting to unrelated domains. Same backend as redirect-chain-analyzer with HTTPS-hardening SEO framing.
Common use cases
- •Measure download and upload speed
- •Test open ports on a home router or server
- •Trace routing paths to diagnose latency
Why use VSPIC for ?
- Full ordered chain proves HTTP to HTTPS upgrade path.
- crossDomain flags apex, www, and CDN canonicalization hops.
- Per-hop status codes — 301 versus 302 semantics for caching.
- finalUrl documents landing point after all redirects.
- Honest note — no JavaScript or meta refresh redirects.
- Free trace for URLs you are authorized to fetch.
HTTPS redirect requirements
Modern security baselines expect plaintext HTTP to redirect permanently to HTTPS before HSTS preload. Missing redirects allow sslstrip on first visit. Search engines treat redirect chains as crawl budget consumers — ideally one 301 from http to https apex.
redirectCount zero on http:// input means no upgrade — critical finding. Multiple hops may still reach HTTPS but slow clients and SEO.
Reading chain and crossDomain
chain array lists step number, url, status, and location per hop. First hop from http:// often shows 301 with location https://. crossDomain true when startHost differs from endHost — common for www to apex consolidation.
Unexpected crossDomain to unrelated brands warrants investigation — possible misconfiguration or compromise.
Relationship to redirect-chain-analyzer
Both call action redirect-chain with identical JSON. redirect-chain-analyzer frames general SEO hop tracing; https-redirect-checker frames TLS upgrade verification language.
API: GET /ip-tools/api/extended?action=redirect-chain&url=http://example.com
301 versus 302 for HTTPS upgrades
Permanent 301 signals browsers and search engines to prefer HTTPS directly next time. Temporary 302 during maintenance is acceptable briefly — production should settle on 301 for upgrade hops.
Document status codes in infrastructure tickets when fixing redirect middleware.
JavaScript and meta refresh gaps
Sites using client-side-only HTTPS upgrade show redirectCount zero on HTTP URL while browsers still reach HTTPS via JS. note field states manual redirect limit — use devtools Network tab for client-side hops when this tool shows no chain.
Pair with security-headers-checker for HSTS after confirming HTTP redirect exists.
CDN and load balancer layers
Edge rules may redirect before origin responds. Trace customer-facing URL including CDN hostname. Multiple crossDomain hops through short link domains may be intentional marketing flows — verify against policy.
After CDN onboarding, rerun http and https variants of apex and www.
HSTS complement
Redirects protect first visit; HSTS protects repeat visits. hsts-preload-checker and security-headers-checker validate Strict-Transport-Security after redirect chain confirms upgrade path.
Preload submission requires working redirect plus HSTS header on HTTPS response.
Responsible URL fetching
Trace URLs you own or may fetch per policy. SSRF-safe validation blocks internal network targets.
We do not permanently store traced URLs.
Important notes & limitations
- HTTP 3xx only — not JavaScript or meta refresh upgrades.
- Does not validate TLS certificate quality after redirect — use ssl-grade.
- Unauthenticated fetch — cookie-gated redirects may differ from browsers.
- Twelve hop cap — long loops truncate with partial chain.
- Server-side fetch — not identical to every browser cache.
Frequently Asked Questions
Yes. VSPIC offers this HTTPS redirect checker at no cost with no account required. Results load in real time.
We do not permanently store your queries on our servers. Some tools run entirely in your browser; others fetch public data for the request only.
Yes. Open the page in any modern phone or tablet browser. Results work on Wi‑Fi and mobile data.
Yes. Enter http:// URL and review chain hops and finalUrl. redirectCount zero means no HTTP-level redirect occurred.
redirect-chain with the url parameter.
Same redirect-chain API and JSON. This page emphasizes HTTPS upgrade verification SEO framing.
No. Only HTTP 3xx Location hops up to twelve steps. Client-side upgrades require browser devtools.
Start hostname differs from final hostname after redirects — expected for www consolidation, review when unexpected.
No. It traces redirects only. Use ssl-grade or ssl-expiry-checker on the final HTTPS URL.
