Question

Is it possible to determine whether website is online or offline other than using HttpWebRequest command?

Please do not suggest me using Ping method because I want to check website availability.

You should send an ajax call to your header (domain). Add random number after the ? (this is to test even if you’re page is cached). This is how it is in javascript:

function hasInternets() {
    console.log("hasInternets: " + window.location.href.split("?")[0] + "?" + Math.random());
    var s = $.ajax({ 
        type: "HEAD",
        url: window.location.href.split("?")[0] + "?" + Math.random(),
        async: false
    }).status;
        console.log("s: " +s);
    //thx http://www.louisremi.com/2011/04/22/navigator-online-alternative-serverreachable/

    return s >= 200 && s < 300 || s === 304; }

If you’re looking for C# codes on this, at least this javascript method will give you an idea.
