Trace the HTTP Redirect Path of a URL
Map every intermediate step in a redirect chain. Identify 301, 302, 307, and 308 response status codes, resolve destination URLs, and identify redirect loops and unnecessary chains that can add latency and crawling overhead.
What is a URL Redirect?
A server instruction directing a client browser or agent to fetch an alternate location rather than the initial URL requested.
The Invisible Detour
When requesting a resource, a web server can issue a 3xx HTTP status code alongside a Location header to specify a different path. Browsers automatically fetch this subsequent path. Standard operations (such as enforcing HTTPS) may use individual redirects safely. However, nesting multiple jumps results in a redirect chain. This pattern introduces load latency, increases connection handshakes, and can reduce crawling efficiency.
Why Trace Them?
During domain migrations, content structure updates, or when auditing tracking links, tracing ensures the final destination is valid and prevents configuration errors that lead to browser-halting redirect loops (A → B → A).
Server-Side vs Client-Side
This analyzer detects HTTP Response Header redirects (301, 302, 303, 307, and 308). It is not designed to evaluate client-side logic such as JavaScript execution (window.location) or inline HTML Meta Refresh tags, which require script engines to run.

Understanding Redirect Status Codes
Different status codes signal distinct server behaviors. Standard practices suggest choosing the status match for your specific routing goal.
| Code | Name | SEO Impact & Behavior | When to Use |
|---|---|---|---|
| 200 | OK | Successful HTTP response. The server returned a successful HTTP response and no further redirect Location header was followed. | The final target page of a trace. |
| 301 | Moved Permanently | Permanent redirect. Search engines process this as a strong signal that the target URL should be treated as canonical. | Site migrations, retired old directories, or canonical hostname structures. |
| 302 | Found (Temporary) | Temporary redirect. Search engines treat this as a weaker canonicalization signal and typically continue displaying the starting URL. | Temporary service location, localized dynamic routing, or short-term maintenance. |
| 307 | Temporary Redirect | Temporary redirect. Operates similarly to a 302, but guarantees that the request method (POST, GET) remains unmodified. | Redirecting dynamic HTTP operations or temporary API submission endpoints. |
| 308 | Permanent Redirect | Permanent redirect. Operates similarly to a 301, but guarantees that the request method remains unmodified during transfer. | Permanent transfers for APIs or stateful POST interfaces. |
| 404 | Not Found | Resource missing. The request reached a non-existent route, preventing successful validation. | Broken references or target paths that need correction. |
Common Redirect Issues and Fixes
Resolutions for common anomalies observed during tracing.
Long Redirect Chains
Multiple consecutive steps add page response delay and overhead.
Fix: Update links or redirect rules to point directly to the final target URL, bypassing intermediate nodes.
Redirect Loops
A back-and-forth mapping configuration triggers `ERR_TOO_MANY_REDIRECTS` in modern browsers.
Fix: Inspect rule definitions for conflicting logic, such as concurrent HTTPS enforcement and localized HTTP fallbacks.
Incorrect 302 Implementation
Using temporary status tags for long-term changes can cause index mismatching.
Fix: Change the routing instruction configuration to return a 301 or 308 code in your server configuration or application routing module.
Nested HTTP to HTTPS Chains
Multiple hops resolving HTTP, subdomains, and protocol transitions sequentially.
Fix: Configure server-wide redirection rules to point raw incoming HTTP directly to final secure HTTPS variants in a single hop.
Undetected JavaScript Redirects
A 200 status is returned, but browser views navigate forward programmatically.
Reality: This indicates client-side execution via JS or HTML meta elements, which are not evaluated by header-based inspectors.
Bot Protection Failures
Attempts return status failures such as 403 Forbidden or 503 Service Unavailable.
Reality: This tool cannot bypass bot detection systems (e.g., Cloudflare, WAFs). If you own the site, examine your security access permissions.

This utility traces standard HTTP transport-level redirect response headers:
- ✓ Follows HTTP 3xx responses with Location headers, including 301, 302, 303, 307, and 308 for up to 10 sequential hops.
- ✓ Resolves protocol-relative and relative target paths encountered in location headers.
- ✓ Detects repeated redirect URLs and stops tracing safely.
- ✓ Does NOT parse client-side scripts, meta refresh headers, or canvas actions.
- ✓ Does NOT override active CAPTCHAs, bot blocks, or secure firewalls.
- ✓ Does NOT log or store individual URL query entries within backend database configurations.

Four steps from input validation to target reporting.
Enter URL
Provide the starting address including standard `http://` or `https://` protocol indicators.

Review every status transition and final path destination on a diagnostic timeline.
Resolve Anomalies
Identify any chains or loops to update rules in your hosting or app routing config.
Redirect Checker FAQs
Technical definitions of redirection handling.
What is the difference between 301 and 302 redirects?
A 301 Permanent Redirect signals that the relocation is permanent. Search engines typically index the target URL and treat it as canonical. A 302 Temporary Redirect indicates a temporary shift, prompting engines to retain the source URL index.
Why are long redirect chains problematic?
Each additional redirect adds another request and can increase latency. Keeping redirect chains short and linking directly to the final URL where possible reduces unnecessary requests and makes crawling more efficient.
Why does the tool show "200 OK" but my browser loads a different page?
This analyzer traces HTTP response headers. If a site returns a 200 status but runs JavaScript scripts (like `window.location`) or contains meta refreshes to point browsers forward, a headless rendering environment is required to capture the change.
What triggers an infinite redirect loop?
Loops occur when rules form cyclic dependencies (e.g., Route A redirects to Route B, and Route B points back to Route A). This is commonly caused by conflicting CDN configurations, CMS plugins, or server rules.
Can I test internal subnets or local interfaces?
No. To prevent Server-Side Request Forgery (SSRF) threats, this server restricts outbound validation to public routes and blocks private ranges (such as `127.0.0.1`, `10.x.x.x`, `192.168.x.x`, and metadata end ranges).
What are 307 and 308 statuses?
These are contemporary equivalents to temporary (307) and permanent (308) actions. They explicitly require the calling client to retain the HTTP method type during subsequent routing steps, which is useful for form POST processes.
Will the tool process affiliate tracking redirects?
Yes. Many tracking links route requests through consecutive temporary hops. This analyzer lists each sequential header endpoint to confirm the final target output.
Is my submitted URL data saved?
No. Analysis is completed in real-time. This tool does not intentionally store traced URLs in its WordPress application database. Temporary, hashed rate-limit keys are used strictly to manage request volume. Standard hosting or server logs may still apply.
