Redirect Loop Misconfiguration

redirect-loop-misconfiguration

A recurring redirect-policy conflict where HTTP/HTTPS and host canonicalization rules overlap, causing double or chained redirects until clients (e.g., curl or crawlers) observe excess redirects and misbehavior in indexing or navigation.

Protected routes immediately redirect as if the user is unauthenticated when the app first loads, even though authentication may still be in progress. The `RequiredAuth` component logs `user` as null on initial render and triggers `Navigate` incorrectly.

Google Search Console saying that there are too many redirects on my homepage — on my homepage. Tension: I want the redirect to happen to both - http and non-www. Outcome: when i enter `curl -I -L http://fiziokaspars.lv`, i get double redirect.

I have a route `/property/:id` that includes a button which, when clicked, should redirect to `/profile/:id`. Tension: It only seems to fail when trying to redirect from `/property/:id` to `/profile/:id`. Outcome: in console it shows response 404.

the danish one is not expected while the english canonical url is correct — on a Vercel deployment the same main page in danish default language points to 'https://mywebsite.dk/da'. Tension: I am so confused at the issue where canonical link points to '/da' is only happening in production and not development on localhost. Outcome: Your error caused by this code:.

GoException: no routes for location: https://www.example.com.

after signing in , it is redirecting to /sign-in page after signing in — I've been using clerk for authentication but. Tension: even though env is NEXT_PUBLIC_CLERK_AFTER_SIGN_IN_URL=/. Outcome: This seems to have solved the redirects for me.

I keep running into a `net::ERR_TOO_MANY_REDIRECTS` error when I try to access my site at `www.example.io` — setting up my Next.js project hosted on Vercel with a custom domain managed through Cloudflare. Tension: Despite configuring the DNS and SSL settings correctly. Outcome: Turns out Vercel provides documentation about how to fix it for Cloudflare.

I get exception of Invalid saml response. — I redirect the browser then from XYZ app to Keycloak using the redirect URI i get from Identity provider i configured. Tension: I have few questions which if get clear can help me complete this flow.

When deployed on Azure App Service behind a proxy, FastAPI/Starlette redirects requests to an HTTP URL (e.g., HTTP Location header in a 307) instead of preserving HTTPS. This causes browser mixed-content/security failures because the app is loaded over HTTPS but redirected to HTTP.

RedirectResponse goes to "/" without the authentication cookie

When I send an HTTPS request using the Swagger UI. Tension: the redirection then fails. Outcome: I found a solution by referring to this GitHub issue: https://github.com/encode/uvicorn/issues/369.

The Flutter Linux app calling local FastAPI endpoints fails with a DioException [bad response] due to an HTTP 307 (Temporary Redirect). Postman requests succeed, but the app always receives the redirect response.

stripe listen --forward-to localhost:8000/payment/webhook/ still returns 403

Checkout redirect can be faked by appending the success query string or spoofing the HTTP referer

the condition is removed, otherwise a `403 (Forbidden)` error is served — include a direct link to the object in `index.php`. Tension: The bucket policy belows works only when either `0.0.0.0/0` is used instead of the actual IP address or the condition is removed. Outcome: I recieve a `200` response if I send a curl request via terminal.

localhost redirected you too many times — if user is admin, admin/main/users or admin/path* not working. Outcome: not-admin redirecting is working.

Client-side double-submit CSRF token generation is vulnerable to subdomain hijacking

All routes except /login redirect back to /login

The Heroku-hosted MERN app receives many automated-looking requests from the same forwarded IP in the same second, with suspicious query/path content (e.g., unexpected “if”/“php” strings). This behavior appears to be scanning or an attack proxy and raises concerns about security and abuse.

502 "Bad Gateway nginx/1.20.1"-Error — Now when I enter http://localhost there is warning if I rly trust the website. I say yes and now I´m on https://localhost. Tension: it usually should open Prefect UI but I have a 502 "Bad Gateway nginx/1.20.1"-Error. Outcome: I would like to run Prefect over https.

a single Cypress test cannot span across multiple origins — we are just trying to test that clicking that button redirects to the correct URL. Tension: instead of allowing the redirect and attempting to read the new URL, we tried to stub the redirect, block it and read what the application is trying to. Outcome: Once the stub is in place, I clicked the button to invoke the method.

Accessing https://example.com results in a “too many redirects” loop, while other domain variants redirect correctly for a React app served by Apache with Cloudflare-managed DNS/SSL.

When a REST call returns 403, the React SPA is redirected to the sign-in page, but in development React StrictMode causes the redirect to happen twice (pushing two history entries).

After signing in, middleware redirection occurs, but the browser URL remains unchanged (e.g., it doesn't update to the intended callback/protected route).

After configuring OAuth2 client login, requests to secured endpoints fail and Spring Security redirects to the login page via form login instead of completing OAuth2 authentication.

I see multiple redirects in the network tab. I have this error: ERR_TOO_MANY_REDIRECTS — I'm working on a REST API using Java 21 with Spring Boot 3.3, and I'm trying to implement authentication through an external site using OpenID.

In Next.js 15 App Router server actions, calling `redirect()` inside a `try/catch` causes `NEXT_REDIRECT` to be thrown and then swallowed by the `catch`, preventing the redirect from happening.

Wget before 1.21.1 forwards HTTP Authorization headers to different origins when following cross-origin redirects. — when following cross-origin redirects. Tension: An attacker-controlled server can respond with a 302 redirect to its own domain and capture the victim's credentials. Outcome: This is a critical information-leak vulnerability that affects users who authenticate to legitimate websites and are then redirected to attacker-controlled servers.

curl versions prior to 7.71.0. Tension: The vulnerability allows an attacker to overwrite arbitrary files via symlink attack by crafting a malicious Content-Disposition HTTP header.

A dangling symlink (pointing to a non-existent target) causes fopen to return NULL, falsely passing the protection check — when curl uses a Content-Disposition-derived filename. Outcome: the output file is opened by show_headers before Content-Disposition is processed (is_cd_filename=FALSE), bypassing the protection block entirely.
