打开 Global.asax.cs 在最上面添加一行 using System.Text.RegularExpressions;

然后在 Application\_BeginRequest 事件中写入

![None.gif][] string  strRawUrl  =  HttpContext.Current.Request.RawUrl;  
![None.gif][] string  strNewUrl;  
![None.gif][]  
![None.gif][] if  (Regex.IsMatch(strRawUrl,  @" default.aspx " , RegexOptions.IgnoreCase))  
![ExpandedBlockStart.gif][None.gif]![ContractedBlock.gif][None.gif] ![dot.gif][] \{  
![InBlock.gif][None.gif]strNewUrl = Regex.Replace(strRawUrl, @"default.aspx", @"showforum.aspx\\?fld=1");  
![InBlock.gif][None.gif]  
![InBlock.gif][None.gif]HttpContext.Current.RewritePath( strNewUrl );  
![ExpandedBlockEnd.gif][None.gif]\}   
![None.gif][] else   if  (Regex.IsMatch(strRawUrl,  @" (\\d+)0(\\d+)0(\\d+)0(\\d+).html " , RegexOptions.IgnoreCase))  
![ExpandedBlockStart.gif][None.gif]![ContractedBlock.gif][None.gif] ![dot.gif][] \{  
![InBlock.gif][None.gif]strNewUrl = Regex.Replace(strRawUrl, @"(\\d+)0(\\d+)0(\\d+)0(\\d+).html", @"showtopic.aspx\\?tid=$1&tpg=$2&bpg=$3&fld=$4");  
![InBlock.gif][None.gif]  
![InBlock.gif][None.gif]HttpContext.Current.RewritePath( strNewUrl );  
![ExpandedBlockEnd.gif][None.gif]\}   
![None.gif][] else   if  (Regex.IsMatch(strRawUrl,  @" showtopic.aspx\\?tid=(\\d+)&tpg=(\\d+)&bpg=(\\d+)&fld=(\\d+) " , RegexOptions.IgnoreCase))  
![ExpandedBlockStart.gif][None.gif]![ContractedBlock.gif][None.gif] ![dot.gif][] \{  
![InBlock.gif][None.gif]strNewUrl = Regex.Replace(strRawUrl, @"showtopic.aspx\\?tid=(\\d+)&tpg=(\\d+)&bpg=(\\d+)&fld=(\\d+)", @"$10$20$30$4.html");  
![InBlock.gif][None.gif]  
![InBlock.gif][None.gif]HttpContext.Current.Response.Redirect( strNewUrl );  
![ExpandedBlockEnd.gif][None.gif]\}   
![None.gif][]  
![None.gif][]

第一个IF是最最简单的

第二个IF是当IIS把HTML交给ASP.NET时使用的，嘿嘿

第三个IF是为了解决表单提交时IE的地址栏出现真实的URL地址，是第二个IF的逆操作

其中正则表达式里的0是分隔符，因为页数、ID的最小址都不可能是0  
用户IE的地址栏中显示的是[http://localhost/AdNT/4561230100101.html][http_localhost_AdNT_4561230100101.html]  
但实际上是[http://localhost/AdNT/showtopic.aspx?tid=456123&tpg=10&bpg=1&fld=1][http_localhost_AdNT_showtopic.aspx_tid_456123_tpg_10_bpg_1_fld_1]
