更多关于Transfer()的细节，它实际上是Server.Execute() + Response.End()，它的源代码如下(来自Mono/.net 4.0):

public void Transfer (string path, bool preserveForm)
{
    this.Execute (path, null, preserveForm, true);
    this.context.Response.End ();
}

对于Execute()，它要运行的是给定路径的处理程序，参见

ASP.NET does not verify that the current user is authorized to view the resource delivered by the Execute method. Although the ASP.NET authorization and authentication logic runs before the original resource handler is called, ASP.NET directly calls the handler indicated by the Execute method and does not rerun authentication and authorization logic for the new resource. If your application's security policy requires clients to have appropriate authorization to access the resource, the application should force reauthorization or provide a custom access-control mechanism. You can force reauthorization by using the Redirect method instead of the Execute method. Redirect performs a client-side redirect in which the browser requests the new resource. Because this redirect is a new request entering the system, it is subjected to all the authentication and authorization logic of both Internet Information Services (IIS) and ASP.NET security policy. -from MSDN

除了ScarletGarden的评论，你还需要考虑搜索引擎和你的重定向的影响。这个页面永久移动了吗?暂时的?这很重要。

看:响应。重定向vs。“301永久移动”:

We've all used Response.Redirect at one time or another. It's the quick and easy way to get visitors pointed in the right direction if they somehow end up in the wrong place. But did you know that Response.Redirect sends an HTTP response status code of "302 Found" when you might really want to send "301 Moved Permanently"? The distinction seems small, but in certain cases it can actually make a big difference. For example, if you use a "301 Moved Permanently" response code, most search engines will remove the outdated link from their index and replace it with the new one. If you use "302 Found", they'll continue returning to the old page...

如上所述，有许多不同之处。除此之外，还有一个不同。Response.Redirect()可用于将用户重定向到不属于应用程序的任何页面，但Server.Transfer()只能用于在应用程序内重定向用户。

//This will work.
Response.Redirect("http://www.google.com");

//This will not work.
Server.Transfer("http://www.google.com");

Response.Redirect()会将您发送到一个新页面，更新地址栏并将其添加到浏览器历史记录中。在浏览器上，您可以单击返回。

Server.Transfer()不会更改地址栏。你不能反击。

当我不想让用户看到我要去哪里时，我使用Server.Transfer()。有时在“加载”类型的页面上。

否则，我将总是使用Response.Redirect()。

服务器之美。转移是你可以用它做的:

TextBox myTxt = (TextBox)this.Page.PreviousPage.FindControl("TextBoxID");

只要使用Server，就可以使用上述方法从上一页获取任何内容。转移但不响应。重定向

Response.Redirect Response.Redirect() will send you to a new page, update the address bar and add it to the Browser History. On your browser you can click back. It redirects the request to some plain HTML pages on our server or to some other web server. It causes additional roundtrips to the server on each request. It doesn’t preserve Query String and Form Variables from the original request. It enables to see the new redirected URL where it is redirected in the browser (and be able to bookmark it if it’s necessary). Response. Redirect simply sends a message down to the (HTTP 302) browser.

Server.Transfer Server.Transfer() does not change the address bar, we cannot hit back.One should use Server.Transfer() when he/she doesn’t want the user to see where he is going. Sometime on a "loading" type page. It transfers current page request to another .aspx page on the same server. It preserves server resources and avoids the unnecessary roundtrips to the server. It preserves Query String and Form Variables (optionally). It doesn’t show the real URL where it redirects the request in the users Web Browser. Server.Transfer happens without the browser knowing anything, the browser request a page, but the server returns the content of another.
