How do I make a node.js TCP connection reconnect automatically? -

-

I wrote a TCP client and server in node.js. I can not understand that the way to reconnect the client is disconnected for any reason. I understand that I have to handle the 'closed' event, but it is an incident that only gets removed when the connection is closed gracefully

here So far the code I have made is: 

  function connect () {client = new net. Socket (); Client.connect (config.port, config.host, function () {console.log ('connect to server');}); Client.on ('close', function () {console.log ('linked to server') '; connect ();}); client.on ('error', ...); // What do I do with this? Client.on ('timeout', ...); // What is this event? I do not understand}   
 Can anyone explain what I can do in the  error  and  timeout  ? And how do I know that the network has disconnected and reconnected?  
  
 
 
 You may only see  error  event handler for no-op / blank function In the form, even after  error ,  close  event for TCP sockets is always emitted, you ignore it unless you want to log error or anything useful You can.  
 In addition, event handlers pass near a boolean  hariser  argument indicates that the socket was due to a closed error and not a normal connection.  
 The incident is set to be used to determine the loss of traffic between two endpoints (i.e. between the middle.

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
