To obtain a client's real IP address through a proxy server, use Request.ServerVariables ("Http_x_forwarded_for") to read it. Note, however, that not every proxy ser

js| clients in the B/s structure of the system, we often need to obtain some information on the client, such as IP and Mac, in conjunction with authentication. In ASP.net, it's easy to get a server-side Mac, but it takes a lot of effort to get the MAC address of the client, usually by calling Win32API or calling the nbtstat command directly, and there are many problems with that, and the other way is to use client script directly, We use JavaScript he

Asp.net| Tips The method of obtaining the IP address of the server is simple and practical by DNS method, as follows: private void Buttonip_click (object sender, System.EventArgs e){system.net.ipaddress[] AddressList = Dns.gethostbyname (Dns.gethostname ()). AddressList;if (addresslist.length>1){textlip.text = addresslist[0]. ToString ();Textsip.text = addresslist[1]. ToString ();}Else{Textlip.text = addresslist[0]. ToString ();Textsip.text = "no connections available";}} Another way to get the

Use C # to invoke an external ping command to obtain network connectivity In the past, when playing Windows 98, several computers connected, need to test the network connection is normal, often use a command is Ping.exe. It feels pretty practical. Now. NET provides us with a powerful function to invoke external tools, and through redirecting input, output to obtain execution results, the following is an exa
