Examine the following code.

function getData() {
    var url = "ajaxdata/citStudents.txt";
    var request = new XMLHttpRequest();
    request.open("GET", url);
    request.onreadystatechange = function() {
        if (request.readyState == 4 && request.status == 200) {
           alert(request.responseText);
        }
    };
    request.send(null);
}

What does it mean if the condition (request.readyState == 4 && request.status == 200) evaluates as true?
