HTTP/HTTPS Misredirect Loops

http-https-redirect-loop

Mixed HTTP/HTTPS configuration makes browsers and edge proxies bounce requests across redirect targets until the redirect limit is hit, causing net::ERR_TOO_MANY_REDIRECTS and blocked API calls; fixes usually align scheme and TLS mode consistently end-to-end.

MATCHESSolution

Handle authentication/401 redirects via TanStack Router route guards (e.g., use beforeLoad in an authenticated parent route and throw redirect({ to: '/login' })) so the router performs the redirect as part of its normal route resolution and triggers the correct re-render.

MATCHESSolution

use https://localhost:5000 and not http://localhost:5000 — sameSite: 'none', secure: true. Outcome: Then you need to use https://localhost:5000 and not http://localhost:5000.

MATCHESSolution

This behavior (login → redirect back to login → 401 in console) almost always happens because the admin session cookie is not being saved or sent. — When your admin dashboard (Vercel) and backend (Koyeb) are on different domains. Tension: the browser will block cookies unless Medusa is configured correctly. Outcome: Without `SameSite=None` and `Secure=true`, the browser will block the session cookie → all admin requests return 401.

MATCHESSolution

It should be fixed as of version 13.2.3 and above — If you're wondering what was causing this issue. Tension: If you really have to use a version that has this issue. Outcome: you can use Joseph Schmoe's solution with `redirect`.

MATCHESSolution

Clear the cookies and test it — on another browser. Tension: private routes all redirect to the home page. Outcome: it went trough just fine.

MATCHESSolution

enable "SSL/TLS Strict" Option, instead of just "Full" — Cloudflare's SSL/TLS encryption mode. Tension: I also turned off page redirects in Cloudflare, as I already handle this in Vercel. Outcome: Vercel has documentation on how to integrate with Cloudflare, which was also helpful in resolving this problem.

MATCHESSolution

And HTTP Client errors (if you're using `HttpClient` or `HttpClientFactory`) — On ASP.NET Core. Tension: you just need to opt-in. Outcome: options.CaptureFailedRequests = true;.

MATCHESSolution

You can configure Nginx to block any request that has an Invalid HTTP_HOST header — server { listen 80; server_name example.com;. Tension: while filtering out requests with invalid host headers at the proxy server. Outcome: return 444;.

MATCHESSolution

Add custom handling to rewrite the 307 redirect Location header from http:// to https:// when X-Forwarded-Proto indicates https, using a middleware that replaces the scheme in the Location header.

MATCHESSolution

Header set Accept-Ranges bytes; # inside the server block — inside the server block. Tension: proxy_force_ranges on; # inside the location block. Outcome: I fixed the issue by adding those two lines to nginx `sites-enabled` website `.conf` file.

MATCHESSolution

fetch(url, { method: 'POST', redirect: 'follow'}) — frontend app is configured to follow the server-side redirect. Tension: not being automatically redirected. Outcome: fetch(url, { method: 'POST', redirect: 'follow'}).

MATCHESSolution

There's no simple solution to this. — when redirection is required. Tension: this doesn't really solve the issue when redirection is required. Outcome: I would try using the redirect `if_required` option.

MATCHESSolution

Chrome will try to connect via HTTPS first with a 3-second timeout. — When browsing in Incognito mode. Tension: If the site takes longer than 3 seconds to load, it will fall back to HTTP and display a warning. Outcome: This doesn’t affect every site, only those that take more than 3 seconds to respond.

MATCHESSolution

Set-Cookie: Path=/; Domain=.example.com — Cookies coming from app.example.com can be sent to api.example.com. Tension: third-party blocking default policy on browsers nowadays. Outcome: look for the cookie header in the request.

MATCHESSolution

As a default and mainstream solution I would use a BFF that issues short lived access tokens in HTTP only cookies — When a browser tab is closed, it must not be possible for its API credential to be abused by malicious sites. Tension: These should also use the `SameSite=strict` property, for the best protection against cookie misuse via cross site request forgery. Outcome: These should also use the `SameSite=strict` property.

MATCHESSolution

HttpClient.GetAsync(new Uri(TextHelper.RedirectUrlNull(urlContent))); — We have an issue in our solution (we are using .net core). Tension: the SNYK vulnerabilities scaner show us that we have a Server-Side Request Forgery (SSRF) vulnerability.

MATCHESSolution

The solution is to redirect the 497 error to 444. — when accessing this port through http. Tension: any access through IP will be blocked.

MATCHESSolution

Your application should listen for HTTP requests only — Heroku's load balancer and routers take care of the HTTPS connection. Tension: Heroku doesn't do this for you. Outcome: Your application just needs to redirect URLs that start with `http://` to `https://`.

MATCHESSolution

Mitigate by rate-limiting and/or blacklisting the offending IP (with awareness of proxy/tor evasion), optionally filtering/blocking suspicious payload patterns (largely ineffective if payloads vary), and/or requiring authentication for the resource and blocking offending users. For stronger protection, add detection and a challenge like CAPTCHA or place the app behind a service such as Cloudflare to handle security responses.

MATCHESSolution

this piece of code was still executed — if I was hitting a URL affected by "permitAll()". Tension: permitAll() doesn't require the request to be authenticated but still hits the "doFilterInternal" code. Outcome: Found the problem.

MATCHESSolution

You can set you client Transport to use both Transport.TLSClientConfig and Transport.DialTLSContext. Outcome: TLSClientConfig should be used for connections to destination HTTPS server and DialTLSContext - for connection to your HTTPS proxy.

MATCHESSolution

You can limit TLS sniffing using certificate pinning. — for some situations, it's worth the trouble. Tension: Google does not recommend this because it's hard to manage. Outcome: See also HTTP Toolkit's discussion on the topic.

MATCHESSolution

Resolve the conflict by handling redirection consistently in Cloudflare (and/or disabling the Apache redirect for the same purpose), then set Cloudflare SSL/TLS encryption to Full (Strict) so HTTPS upgrades and redirects complete without looping.

MATCHESSolution

Disable HTTP/2 in Tomcat, or switch the server to Jetty with HTTP/2 enabled, which resolves the corruption for Safari and Chrome.

MATCHESSolution

redirect-uri: "https://localhost:41448/redirect-uri" — Here’s my application.yml configuration:.

MATCHESSolution

Fixed 30s retry on 429 keeps hammering. — when clearly rate-limited. Tension: keeps hammering. Outcome: Exponential backoff + hard rejection during cooldown.

MATCHESSolution

Move the `redirect()` call outside the `try/catch` (e.g., set a success flag and redirect after the block), or in the `catch` re-throw only redirect-related errors so they can propagate.

MATCHESSolution

Wget before 1.21.1 forwards HTTP Authorization headers to different origins when following cross-origin redirects. — when following cross-origin redirects. Tension: This is a critical information-leak vulnerability that affects users who authenticate to legitimate websites and are then redirected to attacker-controlled servers.

MATCHESSolution

Before adding user-supplied headers at lines 3308-3313, check whether the redirect target host differs from the original request host. Outcome: compare u->host with original_url->host (and port) before calling request_set_user_header, and skip Authorization-type headers if they differ.

MATCHESSolution

Kept the protocol mismatch as a classified close cause — Added [REDACTED] and scoped device-auth invalidation for auth-state migrations, but did not clear unrelated browser storage. Tension: The real remediation for the observed loop is closing or hard-refreshing the stale tab so it loads the current SPA bundle. Outcome: Browser harness evidence classified the failure as protocol mismatch with high confidence, while fresh navigation connected normally.
