Node.JS Multiple User inteaction -

-

I have just started appearing in the node. JS is very interested in knowing and how and if it is possible for many users to interact.

Right now I am trying to get a static HTML page so that a variable = a = 0; Every time A is clicked with a very simple onclick listener.

What do I think and some other knowledgeable person can tell me whether it is possible to open that page on two devices, tell my laptop and my phone and update the variables on both screens Click to increase and increase the number.

Is this something easy? (How is it "simple"? What will it be, without the database and just with javascript? Can someone tell me in the direction of research because I am currently feeling my way around without direction I generally know that this will be a database based feature, but I do not need to be firmly literate, only when the page is open, the value should be "missed".

You should try socket.io with it.

With the function socket.emit and socket. You can trigger the event server-side from client-side and vice versa.

Chat here for a simple example, hope it will help you

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
