AntiPattern

Redirect and Canonical Loops

redirect-and-canonical-loop-mismatch

Mismatched URL schemes and SEO canonical/route configuration cause browsers and crawlers to bounce between incompatible endpoints, leading to redirect loops (e.g., ERR_TOO_MANY_REDIRECTS) and inconsistent resource loading or indexing.

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 hash-based routing — react + tanstack router + github pages. Tension: The default "browser" routing will exhibit the behaviour you describe.

MATCHESSolution

Set redirect_slashes=False and add both "" and "/" route decorators so both /api/users and /api/users/ work reliably

MATCHESSolution

Go to Vercel Dashboard -> Select your project. — Navigate to Settings -> Domains. Tension: Remove redundant redirects from next.config.ts to avoid conflicts. Outcome: Find `fiziokaspars.lv`, click the three dots, and select Redirect to `www.fiziokaspars.lv`.

MATCHESSolution

Verify whether there is Actually `noindex` (or similar) metatag in your webpages — Google Search Console Dashboard. Tension: they can crawl but can not be indexed by Google. Outcome: Please make sure to examine Your level of `robots. txt` if showing `Disallow: /`.

MATCHESSolution

Sitemap resubmission and re-indexing for the affected pages will be necessary. — now they can crawl but can not be indexed by Google. Outcome: Sitemap resubmission and re-indexing for the affected pages will be necessary.

MATCHESSolution

Upgrade Angular to a version where the CommonEngine bug is fixed, and switch SSR rendering to use AngularNodeAppEngine with server-side routing enabled (instead of CommonEngine). Configure the server routing/app engine accordingly so parameterized routes resolve on direct requests.

MATCHESSolution

You can't have same canonical for different page. — Page with different purposes should have their own canonical. Tension: don't use canonical www.site.com/about for different page like contact page, home, page etc. Outcome: Use canonical www.site.com/about for about page even with different languages like www.site.com/about-us, www.site.com/about-ar etc.

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

to your GoRouter. Outcome: You could also try to use the redirect function.

MATCHESSolution

Rename the server actions directory to a non-reserved name (i.e., not `/api`); after renaming, Links returned to proper client-side navigation and full reloads stopped.

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

Remove the trailing slash from the request URL (ensure the endpoint path matches what Postman uses) so the server no longer returns a 307 redirect.

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

-browser back button = the customer should get redirected back to your endpoint — To loop back to your issue:. Tension: you could implement it to handle a second visit after Session creation differently.

MATCHESSolution

not redirect if the URL is already `/admin/main/users` — if ( adminconfig?.matcher.includes(pathname) || pathname.startsWith("/admin/") ) {.

MATCHESSolution

I have a bunch of `Link`s in my landing page. Tension: What I really hope for is that Google crawler can discover each of the pages. Outcome: This is perfectly fine for SEO.

MATCHESSolution

Option 2 is often preferred within the same domain — making AJAX calls. Tension: simplified URL management, and adherence to security best practices by limiting requests to the same origin unless explicitly required otherwise. Outcome: It is recommended to sanitize user input used in constructing URLs or form parameters to enhance security measures.

MATCHESSolution

Decide what your root location is. Tension: No server (remote or localhost), no Javascript fetching (static links), no JQuery, no HTTP(S). Outcome: that's equally trusted to browse the local system by auto generating the links as index.html.

MATCHESSolution

You should be using relative paths. — render a set of "common" routes both under the root `"/"` path and also under the `"/admin"` path. Tension: This will allow you to move a route around anywhere and it will always match relative to its parent route.

MATCHESSolution

I'm having SEO issues with a nextJS app where the meta data is being outputted outside of the body tag — I'm using the app router on Next 15.2.3. Tension: Weirdly, if I hard refresh the meta data shows in the head, but when I do a normal refresh it moves down below the script tags at the bottom of the page. Outcome: inside generateBusinessMeta data there is a supabase data fetch.

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

Use the correct route mounting and handler path so GET /api/weather is matched before the unknown-endpoint middleware

MATCHESSolution

case "CallbackRouteError": return { error: "Invalid credentials!" } — in my `login.ts` server action in the switch case clause. Tension: to return the correct errors. Outcome: bypass this error.

MATCHESSolution

Create index routes for the target parent paths (e.g., routes/$order-id.products._index.tsx and routes/$order-id._index.tsx) and have each loader redirect to the appropriate /local (or /products/local) URL.

MATCHESSolution

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

MATCHESSolution

Use a dedicated pure helper instead of an inline replace. Outcome: accept BOTH path and uri as the locator everywhere you route by file.

MATCHESSolution

using reverse. — return redirect(reverse('ProductSingle', product.slug) + '#SectionInWebsite'). Tension: append "#SectionInWebsite" to the end of the redirect function. Outcome: return redirect(reverse('ProductSingle', product.slug) + '#SectionInWebsite').

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

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.
