### Describe the Bug

I am using middleware in `/functions` to secure some pages. But when the url has double slashes `//`, wrangler doesn't run the middleware for the url.

I have replicated the issue in a [minimal repo here](https://github.com/Shivam010/cloudflare-double-slashes-issue)

---

There's a middleware in `/functions/secure` directory to be applied on all routes of `/secure`.

And the `/out/secure` directory contains a file `one.html` which should be served at `/secure/one` (but first the middleware needs to be invoked)

Now, the **Problem**...

The middleware is properly invoked on `/secure/one` route but not on the `//secure/one`, whenever someone uses a double slash before the middleware directory, wrangler doesn't run the middleware and instead directly serve the pages.

- [`/secure/one?allow` route](https://double-slashes-issue.pages.dev/secure/one?allow) _that's actually allowed by middleware_

Am I missing something here? or is this an actual issue?
