url转发的几个代码!

1 javascript

 

 

2 更简单的框架结构 在一个框架中设置要转发的url

3 c#的url重写实现

 

 

利用IHttpModule实现URL地址转发功能

using System.Web;
using System.Text.RegularExpressions;

    /**////

        }

            this.Rewrite(app.Request.Path,app);
        }

        protected abstract void Rewrite(string requestedPath, HttpApplication app);

    }

    public class ModulRewriter:BaseModuleRewriter
    {
        protected override void Rewrite(string requestedPath, HttpApplication app)
        {
            string strPath = requestedPath;
            string strFileName = strPath.Substring(strPath.LastIndexOf("/")+1);
            string strReg = @"^/d+";
            Regex reg = new Regex(strReg,RegexOptions.IgnoreCase);
            if(reg.IsMatch(strFileName))
            {
                
                string strTruePath = strPath.Remove(strPath.LastIndexOf("/")+1,strFileName.Length);
                strTruePath = strTruePath+"go.aspx?id=" + reg.Match(strFileName).Value;
                HttpContext.Current.RewritePath(strTruePath);

            else
            {

                HttpContext.Current.RewritePath(strPath);
            }
        }

    }
