I've been experimenting with Ajast and it's very useful for getting remote URL sources etc. In the below example it bypasses same-domain-policy and gets "Hello World !", but I cannot recreate this when I change it to google.com.

<html>

    <script id="TestScript" Language="javascript">
      function test()

        xmlhttp.onreadystatechange = function()
        {
          if (xmlhttp.readyState==4) // 4 = "loaded"
          {
            if (xmlhttp.status == 200)
              document.write(xmlhttp.respo开发者_StackOverflow社区nseText);
            else
              alert('ERROR: ' + xmlhttp.status + ' -> ' + xmlhttp.statusText);

My problem occurs when I change the get url to google.com, can anyone help me? I want JavaScript to fetch the source of a page.

Read the documentation.

AJAST can only be used to send a request to a compatible server-side script.
Basically, it's a non-standard form of JSONP.

I thought that dynamicly loading the script into the DOM would bypass this security feature, like the quote suggests

"The main advantage of AJAST is its ability to make requests to foreign hosts (cross domain) which a standard AJAX request cannot do using a technique known as 'the script tag hack'. "

Where would I be able to find documentation as i dont want to use a JSONP proxy, I would like to request the webpage without signing.
