How or is it possible to send a request from a website to a c# program/service/server, work the request and send back the information to the website?
E.G.:
I click on a website on a button to request the remaining disksize of a server patition, the website send the request to the c# program, it works the request and sends back the information to the website. The website noticed the data(with an event or something) and displays it.
