Change URL on onBeforeRequest

问题

I have following code:

chrome.webRequest.onBeforeRequest.addListener(
  function(details) {         

    return { redirectUrl: "http://yahoo.com"};
  },
  {
    urls: [
      'http://google.com'
    ],
    types: ['main_frame']
  },
  ['blocking']);

This is redirecting google.com to yahoo.com. My Question is now howto keep google.com in the addressbar, showing yahoo.com.

My first attempt was to use

chrome.tabs.update(tab.id, {url: details.url});

but that results in an Reloading of the site.

---

WHY?

I am requesting this for pdf.js, since its anoying to loose the PDF URL.

This is not possible, you may simulate this effect by using a 100%x100% frame - but still, your question sounds very malicious.
