How to do readable.pause() in node.js so that readable.on('end', function(){}) is not emitted? -

-

I am consuming a bunch of data in my express node. Js app. Before taking more data, I have to wait to complete one of my operations. 

  req.on ('data', function (data) {req.pause (); do_my_thing (); req .reume ();} req.on ('end', function ( } {do_my_finish_thing}}}   
 The problem is that req.on ('end', () {}) is still called whenever I stop the stream. There is no way to prevent that ('end', () {}) is not emitted?   
 
 
 What you should do, but 'do_my_thing' function will be executed with asynchronous, therefore, it is almost instantaneous  
 You can resume stream in do_my_thing callback:  
  function do_my_thing (callback) {// your work callback () ;} req.on ('data', function (data) {req.pause (); do_my_thing (function () {req.resume ();})}} req.on ('end', function () {do_my_finish_thing }}}

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
