[feature?] Block some of requests

Hi @chrisvfritz!, prerender is awesome project and I’m fascinate of it, but i found one problem which I cant resolve 😕 maybe You can help me 😃 I want to prerender my index.html, who have in body this script:

<script>
  WebFontConfig = {
    google: { families: ['Lato:300,400,400i,700,900:latin'] }
  };
  (function () {
    var wf = document.createElement('script');
    var protocol = ('https:' == document.location.protocol ? 'https' : 'http');
    wf.src = protocol + '://ajax.googleapis.com/ajax/libs/webfont/1.5.18/webfont.js';
    wf.type = 'text/javascript';
    wf.defer = 'true';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(wf, s);
  })();
</script>

It simple get fonts script from google, added to DOM body to improve loading speed and not have block script on start loading a website.

But when prerender plugin render index.html appear for me block script in head section:

<script src="http://ajax.googleapis.com/ajax/libs/webfont/1.5.18/webfont.js" type="text/javascript" defer></script><link href="http://fonts.googleapis.com/css?family=Lato:300,400,400i,700,900&subset=latin" rel="stylesheet" media="all">

Is any possibility to not execute and get data (or replace response with my custom data) for some request, in this example: http(s)://ajax.googleapis.com/ajax/libs/webfont/1.5.18/webfont.js

@radzikowski It’s not possible to replace the response data, but you can prevent third-party requests from being loaded by adding skipThirdPartyRequests: true to the renderer config. In this case, loading fonts is not critical for prerendering, so you should add skipThirdPartyRequests: true.

@radzikowski An allow/deny system for individual URLs would likely be ideal, but I haven’t thought through the best way to get it working consistently in all renderers. Feel free to PR if you have an idea. 😃
