限制每台PC的开放连接. [英] Limit open connection per pc.

问题描述

伙计们，

如何验证网站是否已打开.

我想限制每台PC与我的网站的连接.
如果我的网站已经在用户的PC中打开，然后尝试从另一个浏览器再次打开它，那么我只想关注当前打开的浏览器.


谢谢，

Hernan Cabrera

Guys,

How can I validate if website is already open.

I want to limit connection to my website per pc.
If my website is already open in the user''s pc and try to open it again from another browser then I want to just focus to the currently open browser.


Thanks,

Hernan Cabrera

推荐答案

一个选择是在数据库SQLite或类似模型中注册访问者.您可以检查IP地址:
http://stackoverflow.com/questions/735350/how-to-get-a-users-client-client-ip-address-in-asp-net [ http://stackoverflow.com/questions/6160991/how-to-get-client-machine-name-in-asp-net-c-sharp [使用ASP.NET和C#检测浏览器 [ ^ ]

如果这两个不起作用，我真的不知道您应该怎么做.我真的不明白这是什么意思....

顺便说一句:Mac地址更加麻烦:

One choise is to register the visitors in a database SQLite or something simular. You could check the IP adress:
http://stackoverflow.com/questions/735350/how-to-get-a-users-client-ip-address-in-asp-net[^]

and/or the host name:
http://stackoverflow.com/questions/6160991/how-to-get-client-machine-name-in-asp-net-c-sharp[^]

Get the browser:
Detect the browser using ASP.NET and C#[^]

If those two dosnt work I dont really know what you should do. I dont really see what the point is though....

BTW: Mac Adress it more troublesome:

您好，

更好的方法是在客户端上创建Cookie，并每次检查Cookie.请参阅以下代码段.

Hello,

Better approach is to create Cookies on clients, And check cookie every time. Refer following code snippet.

public bool IsInstanceAlreadyExist()

{

 if (null == System.Web.HttpContext.Current.Request.Cookies["InstanceExist"])

{
 HttpCookie myCookie = new HttpCookie("InstanceExist")

 // Set the cookie value.
 myCookie.Value = "True";
 // Add the cookie.
 System.Web.HttpContext.Current.Response.Cookies.Add(myCookie);
 return false;
}
else
{
    return true;
}
}

并清除Session上的cookie以处理浏览器关闭问题.

And clear the cookie on Session to handle browser close issues.

void Session_End(object sender, EventArgs e)
{
}

谢谢！！！！

Thanks!!!!

肯尼思和维诺德，

我尝试使用global.asax中的变量及其现在的功能.

对于每个登录的用户，我将其连接到global.asax中的变量，但在
之前 我使用instr验证用户是否在变量中.

感谢你们俩.

Hi Kenneth and Vinod,

I''ve tried to use variable from global.asax and its working now.

for each user that login, I concatenate to a variable from global.asax but before
that I use instr to validate if the user is in the variable.

thanks to both of you.
