Answer 1

When you make a request to a server, have it check to see if a progress is not null (or fetching that data) first. If it is fetching data, abort the previous request and initiate the new one.

var progress = null

function fn () {    
    if (progress) {
        progress.abort();
    }
    progress = $.ajax('ajax/progress.ftl', {
        success: function(data) {
            //do something
            progress = null;
        }
    });
}
