Hi,

I'm using Cloudflare Workers to navigate between different applications without changing the host name. However, due to several reasons, I'm not sure if this technique will work as expected unless I add custom domains. The moment I add the custom domain, it changes my base host URL to the one I'm navigating to. Here's why I’m doing this: My website is hosted on Cloudflare Pages, and the other two applications are dynamic apps deployed on separate VMs. Previously, I was handling this with NGINX, but now I want to use Cloudflare Pages for my static site to improve its performance. Unfortunately, I'm stuck with this issue. Below is my worker implementation:

export default {
  async fetch(request) {
    let url = new URL(request.url);

    if (url.pathname.startsWith("/tools")) {
      return fetch(`https://tools.cf.worker.whoisfreaks.com${url.pathname}`, request);
    }

    if (url.pathname.includes("/resources")) {
      return fetch(`https://blogs.cf.worker.whoisfreaks.com${url.pathname}`, request);
    }

    if (url.pathname.includes("/blog")) {
      return fetch(`https://blogs.cf.worker.whoisfreaks.com${url.pathname}`, request);
    }

    if (url.pathname.includes("/_next")) {
      return fetch(`https://blogs.cf.worker.whoisfreaks.com${url.pathname}${url.search ? '?' + url.searchParams.toString() : ''}`, request);
    }

    return fetch(`https://wf-website-1if.pages.dev${url.pathname}`, request);
  }
};

export default {
  async fetch(request) {
    let url = new URL(request.url);

    if (url.pathname.startsWith("/tools")) {
      return fetch(`https://tools.cf.worker.whoisfreaks.com${url.pathname}`, request);
    }

    if (url.pathname.includes("/resources")) {
      return fetch(`https://blogs.cf.worker.whoisfreaks.com${url.pathname}`, request);
    }

    if (url.pathname.includes("/blog")) {
      return fetch(`https://blogs.cf.worker.whoisfreaks.com${url.pathname}`, request);
    }

    if (url.pathname.includes("/_next")) {
      return fetch(`https://blogs.cf.worker.whoisfreaks.com${url.pathname}${url.search ? '?' + url.searchParams.toString() : ''}`, request);
    }

    return fetch(`https://wf-website-1if.pages.dev${url.pathname}`, request);
  }
};

If anyone has any insights or ideas on how to resolve this, that would be greatly appreciated!
