下面的代码实现了检测客户端显示器分辨率、浏览器类型和客户端IP的功能。你可以把客户端信息保存到Session，ViewState等中以便在其它的页面直接使用。

编辑由于某些原因，在我们的应用中会遇到一个用户只能在一个地方登录的情况，也就是我们通常所说的单点登录。在ASP.NET中实现单点登录其实很简单，下面就把主要的方法和全部代码进行分析。
实现思路
利用Cache的功能，我们把用户的登录信息保存在Cache中，并设置过期时间为Session失效的时间，因此，一旦Session失效，我们的Cache也过期；而Cache对所有的用户都可以访问，因此，用它保存用户信息比数据库来得方便。
查看示例

编辑对于加载时间比较长的ASP.NET页面，我们可以在客户端浏览器中显示进度条来显示页面正在装载。下面就是具体的实现过程：
- 新建项目，名字为WebPortal，在项目类型中选择Visual C#项目或者Visual Basic项目都可；
- 在模板类型中选择ASP.NET Web应用程序；
- 位置里输入：http://localhost/WebPortal；
- 添加新项：名字为ShowProgress的Web窗体。
- 在您的Web窗体ShowProgress.aspx上添加任何其他的Web服务器控件。
- 在ShowProgress.aspx上单击右键，点“查看代码”，在最上面输入：
Visual C# .NET代码 <![CDATA[using System.Threading;
]]>Visual Basic .NET代码 <![CDATA[Imports System.Threading
]]>
- 在Page_Load事件里输入： Visual C# .NET代码 <![CDATA[Response.Write("
<div id='mydiv' >");
Response.Write("_");
Response.Write("</div>
");
Response.Write("
<script>mydiv.innerText = '';</script>
");
Response.Write("

Response.Write("var dots = 0;var dotmax = 10;function ShowWait()");
Response.Write("{var output; output = '正在装载页面';dots++;if(dots>=dotmax)dots=1;");
Response.Write("for(var x = 0;x <dots;x++){output += '·';}mydiv.innerText = output;}");
Response.Write("function StartShowWait(){mydiv.style.visibility = 'visible'; ");
