iis - HTTP 403.9 - Access Forbidden: Too many users are connected -

-

I have created an application in VStudio. It was running well in debugging mode, but my computer was slow and slow because I used to work until it was freezed. After manually restarting it, the app was not running in any more debug and I got this app in the browser.

  1. Only I'm connected to the app now.
  2. I restarted the computer, so there is no instance associated with the client
  3. I removed and reset the IIS

What's wrong?

Is this happening on an XP Pro development machine? Occasionally, if you have many JavaScript / images / CSS files, as well as IFrames and many AJAX calls, one of your pages will exit the connection in a development environment. There are two ways to overcome this:

    Close the HTTP-Elevations. In the IIS Manager, go to the Web Site tab and under the connection, uncheck the HTTP Maintain-Elive enabled checkbox. Do not do it in a production environment because it will slow down your site too.

  1. Increase the number of concurrent connections You are limited by design for 10 concurrent connections by default, but it can be extended. First of all, make sure that your default window script is set to the host console (cscript.exe) at the command prompt:

    cscript // h: cscript

< P> Next, let's extend the limit of connections to 40. 

  C: \ Inetpub \ AdminScripts \ adsutil set w3svc / MaxConnections 40

You can make IIS connection timeout more aggressive so that connections do not last long .

Set the default script host back to the window: 

  cscript // h: wscript

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.

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
