Hello, If i run the following code in an ASP page it loads the file (stored on local server) and outputs the text as expected;

<p id="demo"></p>

<button type="button" onclick="loadDoc()">Load Feed</button>

<script>
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      document.getElementById("demo").innerHTML =
      this.responseText;
    }
};
xhttp.open("GET", "XML_TEST.xml", true);
xhttp.send();
}
</script>

I need to run this from a URL not a local file. The URL has the exact same data and if i run the URL in a browser i get the data displayed in XML in the browser but when i change my code to fetch the data from the URL nothing happens.

<script>
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      document.getElementById("demo").innerHTML =
      this.responseText;
    }
};
xhttp.open("GET", "https://test.httpapi.com/api/domains/available.xml?auth-userid=user&api-key=key&domain-name=domain&domain-name=domain2&tlds=com&tlds=co.uk", true);
xhttp.send();
}
</script>

any ideas please how i can get this to work?

This looks to be JavaScript running client side rather than ASP code which would run server side.

Browsers often block client side JavaScript from running cross domain for security to prevent XSS vulnerabilities.

In addition running client side as JavaScript would expose your login credentials to the end user.
