Cannot enforce 301 redirect for multiple slashes due to CDN path normalization

[IvanKalynych]

What is the location of your example repository?

No response

Which package or tool is having this issue?

Oxygen

What version of that package or tool are you using?

"vite": "^6.2.4",

What version of Remix are you using?

"react-router": "7.9.2",

Steps to Reproduce

When requesting:

https://pick-up-shoes.com.ua///////

the response is:

HTTP/2 200

instead of a 301 redirect to:

https://pick-up-shoes.com.ua/

We have URL normalization logic in server.ts (Hydrogen app) that:

collapses multiple slashes

removes trailing slash (except root)

forces lowercase

issues 301 when the normalized path differs

However, the redirect is never triggered for ///////.

// server.ts
// Virtual entry point for the app
import {storefrontRedirect} from '@shopify/hydrogen';
import {createRequestHandler} from '@shopify/hydrogen/oxygen';
import {createHydrogenRouterContext} from '~/lib/context';

/**

• Export a fetch handler in module format.
  */
  export default {
  async fetch(
  request: Request,
  env: Env,
  executionContext: ExecutionContext,
  ): Promise {
  try {
  const url = new URL(request.url);

  let normalizedPath = url.pathname.replace(//{2,}/g, '/');

  if (normalizedPath !== '/' && normalizedPath.endsWith('/')) {
  normalizedPath = normalizedPath.slice(0, -1);
  }

  normalizedPath = normalizedPath.toLowerCase();

  if (url.pathname !== normalizedPath) {
  const redirectUrl = ${url.origin}${normalizedPath}${url.search};
  return Response.redirect(redirectUrl, 301);
  }

  const hydrogenContext = await createHydrogenRouterContext(
  request,
  env,
  executionContext,
  );

  /**
  * Create a Remix request handler and pass
  * Hydrogen's Storefront client to the loader context.
  */
  const handleRequest = createRequestHandler({
  // eslint-disable-next-line import/no-unresolved
  build: await import('virtual:react-router/server-build'),
  mode: process.env.NODE_ENV,
  getLoadContext: () => hydrogenContext,
  });

  const response = await handleRequest(request);

  if (hydrogenContext.session.isPending) {
  response.headers.set(
  'Set-Cookie',
  await hydrogenContext.session.commit(),
  );
  }

  if (response.status === 404) {
  /**
  * Check for redirects only when there's a 404 from the app.
  * If the redirect doesn't exist, then storefrontRedirect
  * will pass through the 404 response.
  */
  return storefrontRedirect({
  request,
  response,
  storefront: hydrogenContext.storefront,
  });
  }

  return response;
  } catch (error) {
  console.error(error);
  return new Response('An unexpected error occurred', {status: 500});
  }
  },
  };

Expected Behavior

301 redirect to:

https://pick-up-shoes.com.ua/

Actual Behavior

When requesting:

https://pick-up-shoes.com.ua///////

the response is:

HTTP/2 200
