javascript - Mixing html5 with non-async tags -

-

After some interesting conversation on Async, I could not find any information about what happened if you followed the regular script tag, followed with an async.

I tried to do a quick test and what do I expect to do this: if I have placed a non-async tag for the first time, it always seems to load it later async Responsible tag Here I am testing that code:

test.html: 

  & lt ;; Doctype html & gt; & Lt; Html & gt; & Lt; Top & gt; & Lt; Title & gt; Trial & lt; / Title & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Script src = "https://code.jquery.com/jquery-2.1.1.min.js" & gt; & Lt; / Script & gt; & Lt; Script src = "test.js" async & gt; & Lt; / Script & gt; & Lt; / Body & gt; & Lt; / Html & gt;   
 test.js:  
  warning (window .jquery);   
 In every case it seems that jQuery loading. Maybe I'm missing something in my tests, is that right? Can I have dependency in the non-async tag and then the dependents who use the async? Is it particularly beneficial to do this?  
 Has anyone found it? What if you had some asyncs and then a non-async? Is loading async'd js?   
 
 
 Block the processing of non-async script tag pages. The browser can look forward and load test.js before jquery is executed, but the browser can not process the script because it does not know what the jquery for the page is (document.witail, window object is changing ..).  
 So, yes it will work  
 By doing so, the page will load slightly faster, because one of the two scripts can be loaded asynchronously. This will probably not match the startup time of the optimization, asynchronous loader.

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
