响应。重定向只是向浏览器发送一条消息(HTTP 302)。

服务器。传输在浏览器一无所知的情况下发生，浏览器请求一个页面，但服务器返回另一个页面的内容。

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 For example, if you use a "301 Moved Permanently" response code, most search engines will remove the outdated link from their index and replace it with the new one.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...

服务器。传输不会改变客户端浏览器中的URL，因此实际上浏览器并不知道您更改了另一个服务器端处理程序。响应。重定向告诉浏览器移动到另一个页面，因此标题栏中的url会发生变化。

服务器。传输稍微快一点，因为它避免了到服务器的一次往返，但不更改url可能对您有好处，也可能有坏处，这取决于您想要做什么。

简而言之:回应。重定向只是告诉浏览器访问另一个页面。服务器。Transfer有助于减少服务器请求，保持URL相同，并且通过一些错误处理，允许您传输查询字符串和表单变量。

我发现并同意以下观点:

Server.Transfer is similar in that it sends the user to another page with a statement such as Server.Transfer("WebForm2.aspx"). However, the statement has a number of distinct advantages and disadvantages. Firstly, transferring to another page using Server.Transfer conserves server resources. Instead of telling the browser to redirect, it simply changes the "focus" on the Web server and transfers the request. This means you don't get quite as many HTTP requests coming through, which therefore eases the pressure on your Web server and makes your applications run faster. But watch out: because the "transfer" process can work on only those sites running on the server; you can't use Server.Transfer to send the user to an external site. Only Response.Redirect can do that. Secondly, Server.Transfer maintains the original URL in the browser. This can really help streamline data entry techniques, although it may make for confusion when debugging. That's not all: The Server.Transfer method also has a second parameter—"preserveForm". If you set this to True, using a statement such as Server.Transfer("WebForm2.aspx", True), the existing query string and any form variables will still be available to the page you are transferring to. For example, if your WebForm1.aspx has a TextBox control called TextBox1 and you transferred to WebForm2.aspx with the preserveForm parameter set to True, you'd be able to retrieve the value of the original page TextBox control by referencing Request.Form("TextBox1").

响应。重定向在第一个页面到达客户端后将页面重定向到另一个页面。所以客户端知道重定向。

服务器。传输退出页面的当前执行。客户端不知道重定向。它允许您传输查询字符串和表单变量。

所以这取决于你的需要来选择哪个更好。

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()。
