Streaming large file uploads to ASP.NET MVC -

-

I'm working for an application, I need to allow the user to upload a very large file - that is Probably many gigabytes - Unfortunately, through our website, ASP.NET MVC appears to load the entire request to load into RAM - not exactly ideal for such an application. Specifically, trying to solve this problem via code: 

  if (request.Method == "POST") {request.ContentLength = clientRequest.InputStream.Length; Var rgbBody = new byte [32768]; (Var requestStream = request.GetRequestStream ()) using {int cbRead; While ((cbRead = clientRequest.InputStream.Read (rgbBody, 0, rgbBody.Length)) gt; {fileStream.Write (rgbBody, 0, cbRead); }}}

The buffer-to-request-in-RAM fails to circumvent the psyche. Is there an easy way to work around this behavior?

It has been found that my initial code was originally correct; Only needed to change 

  request.ContentLength = clientRequest.InputStream.Length;  

  request. Contact lang = clientRequest.ContentLength;

Pre-stream in full request to determine the length of the content; The latter only examines the content-length header, for which only the header is sent in full. This allows IIS to start streaming requests almost immediately, which completely eliminates the original problem.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
