Get Raw Http Response From Ajax

Using plain JavaScript AJAX in a browser, can I get the raw HTTP response from the server? By that I mean headers and body as raw text like: < HTTP/1.1 301 Moved Permanently <

Solution 1:

You will need to combine two calls to get the body and the response headers.

• To get the headers, use getAllResponseHeaders
• To get the body, use property .response when the readystate is 4 (=DONE)

var request = new XMLHttpRequest();
request.open("GET", "http://www.example.com", true);
request.send(null);
request.onreadystatechange = function() {
  if (request.readyState == 4){
    console.log(request.getAllResponseHeaders());
    console.log(request.responseText);
  }
};
