title: can web server send data without a request from client?
body: <p>I have a tool which takes any time from a minute to couple of hours. I want to write a web application to enable users to run the tool from webpage. Since each tool run takes longer time, i want to send the tool run request from the webpage, then i want to update the page with status information. For updating the status information, the client has to poll the server. Is there any way by which server can send the status message to the client without a request </p>
