I've been away from web development for 6/7 years now and I'm completely lost in regards to how to do things. I'm going through some tutorials on HTML5 and whatnot, but I was hoping to get a helping hand here.I'm trying to build a (POC) website which would have the "server" monitor it's running applications and when a certain application is running change the content of a hosted page. I don't want the model to be PageLoad->Application Check, I'd rather have something like ServerStart->ApplicationHook->Callback->Model->PageLoad->CheckModel, so a hook is put in place when the server starts and the callback of the hook updates a model which the page uses to update. Although this architecture may not be the best way, in general I'm just looking for a way to have a long running process which starts when the server starts up. Eventually I'l move this to a Windows service which calls a webservice when changes are made, but for a POC I'd rather keep away from multiple applications interacting, as the Windows Service would need to be "called" by the server too and I can't think of an easy implementation of that at the moment.So, if you were building a page which relied on events on the server and needed to be able to interact with an application on the server separately to an individual page, but the page needs to be able to "post" information back to that application what would you do?My explanation has been a bit all over the place, so I hope at some point my question has come across clearly!
