title: Show "In Progress" during http request (long running) execution in javascript/jquery/php
body: <p>I would like to have "Loading.." / "In Progress.." message during regular http request. This should be shown only during the http request cycle, and once you get the request is completed and you get the response, it should go off. I am keen about regular HTTP Request, and HTTP Request that take longer time and not AJAX. Code blocks, examples, pointers appreciated. Here is one approach, I would like to have common approach, so that it can be used for any http request.</p>
