Asp.Net基于动态页面的静态页面实现

 出处:http://hi.baidu.com/%BA%EC%C3%F1/blog/item/68025ee7807f972cb83820fb.html

只需要在Global.asax加上几行代码就行了,我们是通过捕获用户的请求,然后通过RewritePath来实现的:
这是我程序中的一段代码,它就负责把上面的那些请求转化为真正的页面请求,
我们是通过正则表达式来区分各种类别的请求的:

protected void Application_BeginRequest(Object sender, EventArgs e)
        {                                                                        
            string url= Request.Url.AbsoluteUri ;
            string strMatch= @"http://www/.2shoushichang/.com/([^/]+)/" ;
                        
            string newUrl= "" ;
            string strCmd= SplitInfo(url,strMatch) ;
            if (strCmd!= null)
            {
                switch(strCmd.ToLower())
                {

                    case"product":
                         strMatch= @"/product/(/d+)/.aspx" ;
                        string strProductId= SplitInfo(url,strMatch) ;
                                                
                        if (strProductId!= null)
                        {
                             newUrl= string.Format("..//Product.aspx?id={0}",strProductId) ;
                            this.Context.RewritePath(newUrl) ;        
                         }
                        break ;
                                
                    case"midtype"://s-100100-All-2.aspx
                         strMatch= @"/midtype/(/S+-/d+-/S+-/d+)/.aspx" ;
                        string strResult= SplitInfo(url,strMatch) ;
                                                
                        if (strResult!= null)
                        {
                            string[] strParam= strResult.Split('-') ;//MidtypeList.aspx?id=100100&city=威海&type=s&Page=3
                            if (strParam.Length!= 4)
                                break ;
                            string city= AppGlobal.GetCityNameByCode(strParam[2]) ;
                             newUrl= string.Format("..//MidtypeList.aspx?type={0}&id={1}&city={2}&page={3}",strParam[0],strParam[1],city,strParam[3]) ;
                            this.Context.RewritePath(newUrl) ;        
                         }
                        break ;                                        
                    case"其它处理":
                        break;
                    default:
                        break ;
                 }

             }                        
         }
