Request获取url信息

在ASP.NET编程中经常需要用Request获取url的有关信息，Request中有多种方法获取url信息

连转再载再测如下： 

（一）页面Test.aspx

protected void Page_Load(object sender, EventArgs e)

{

    Response.Write("Request.ApplicationPath：" + Request.ApplicationPath + "<br/>");

    Response.Write("Request.CurrentExecutionFilePath：" + Request.CurrentExecutionFilePath + "<br/>");

    Response.Write("Request.Path：" + Request.Path + "<br/>");

    Response.Write("Request.PathInfo：" + Request.PathInfo + "<br/>");

    Response.Write("Request.PhysicalApplicationPath：" + Request.PhysicalApplicationPath + "<br/>");

    Response.Write("Request.PhysicalPath：" + Request.PhysicalPath + "<br/>");

    Response.Write("Request.RawUrl：" + Request.RawUrl + "<br/>");

    Response.Write("Request.Url.AbsolutePath：" + Request.Url.AbsolutePath + "<br/>");

    Response.Write("Request.Url.AbsoluteUri：" + Request.Url.AbsoluteUri + "<br/>");

    Response.Write("Request.Url.Host：" + Request.Url.Host + "<br/>");

Response.Write("Request.Url.LocalPath：" + Request.Url.LocalPath + "<br/>");

if (Request.UrlReferrer != null)

            Response.Write("上一页的地址：" + Request.UrlReferrer.AbsolutePath);

//UrlReferrer:获取有关客户端上次请求的 URL 的信息，该请求链接到当前的 URL。

}

（二）页面a.aspx

在页面a.aspx中添加对Test.aspx的链接

<a href="Test.aspx" target="_self">点击</a>

（三）访问a.aspx，并点击链接

结果：

Request.ApplicationPath：/web2

Request.CurrentExecutionFilePath：/web2/Test.aspx

Request.Path：/web2/Test.aspx

Request.PathInfo：

Request.PhysicalApplicationPath：E:\test8\Net35\web2\

Request.PhysicalPath：E:\test8\Net35\web2\Test.aspx

Request.RawUrl：/web2/Test.aspx

Request.Url.AbsolutePath：/web2/Test.aspx

Request.Url.AbsoluteUri：http://localhost:20372/web2/Test.aspx

Request.Url.Host：localhost

Request.Url.LocalPath：/web2/Test.aspx

上一页的地址：/web2/la1.aspx

iframe里测了一下，没有变化
