Get index.html response headers

Question

Note: Turns out this is a duplicate: Accessing the web page's HTTP Headers in JavaScript

Is there a way to get the request headers for the index.html request? For example, this is a screenshot of me hitting google.com

I would like to be able to get access to the Request Headers. Is this possible?

What about for other javascript/css assets?

Answer 1

It depends on how are you requesting that page, if you are loading it over ajax with javascript/jquery it is possible:

$.ajax({
    type: 'GET',
    url:'google.com',
    success: function(resp){
        console.log(resp.getAllResponseHeaders());
    }
});

Answer 2

You can try: window.navigator.userLanguage || window.navigator.language window.navigator.userLanguage || window.navigator.language
Or also you can make ajax query.

There are services for this.
Ex: http://ajaxhttpheaders1.appspot.com/?callback=function() {} (JSONP)
