🚀 Feature Request: Override http://placeholder url in miniflare fetch proxy

[bruceharrison1984]

Describe the solution

I'm not exactly sure how this could be done, but when trying to utilize something like Hono OpenAPI from Miniflare, the context object results in a host-relative incorrect URL:

apiV1.doc('/doc', (ctx) => ({
  openapi: '3.1.0',
  info: {
    version: '1.0.0',
    title: 'Torch',
  },
  servers: [{ url: `${new URL(ctx.req.url).origin}/api/v1` }],
}));

This isn't an issue in Production because the correct URL is present in the request. In the case of local development, we don't have access to the true hostname from the context, so there isn't any way to fixup this URL because we don't know what the original hostname was supposed to be.

Does this happen with Wrangler, or when running Miniflare directly?

This is when running Miniflare directly via unstable_dev for use in a Vite plugin.
