C# 中的帧重定向
我想从 IIS 7 的托管模块中用 C# 执行帧重定向。
当我调用 context.Response.Redirect(@"http://www.myRedirect.org"); 时，会显示正确的页面，但浏览器中也会显示地址。这正是我不想要的。
所以我想要这样的东西：
private void OnBeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpContext context = app.Context;
// make a frame redirect if a specified page is called
if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html"))
{
// perform the frame redirect here, but how?
// so something like
context.Response.Redirect(@"http://www.myRedirect.org");
// but as I said that doesn't redirect as I want it to be
}
}
对此有什么想法吗？
编辑： 我尝试了这个例子，所以我有：
private void OnBeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpContext context = app.Context;
// make a frame redirect if a specified page is called
if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html"))
{
// perform the frame redirect here, but how?
context.Response.Write(@"<html>");
context.Response.Write(@"<head>");
context.Response.Write(@"</head>");
context.Response.Write(@"<frameset rows=""100%,*"" framespacing=""0"" frameborder=""NO"" border=""0"">");
context.Response.Write(@"<frame src=""http://www.myRedirect.org"" scrolling=""auto"">");
context.Response.Write(@"</frameset>");
context.Response.Write(@"<noframes>");
context.Response.Write(@"<body>Some text...");
context.Response.Write(@"</body>");
context.Response.Write(@"</noframes>");
context.Response.Write(@"</html>");
}
}
但这也没有正确重定向。我的浏览器中仍然显示重定向地址。那么还有其他想法吗？
编辑： 我显然犯了一个错误。上面的代码可以工作并执行我想要的操作。它首先不起作用，因为我的重定向网址做了一些意想不到的事情。
I would like to execute a frame redirect in C# from my managed module for the IIS 7.
When I call context.Response.Redirect(@"http://www.myRedirect.org");the correct page is shown but also the address is shown in the browser. And that is exactly what I do not want.
So I want something like:
private void OnBeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpContext context = app.Context;
// make a frame redirect if a specified page is called
if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html"))
{
// perform the frame redirect here, but how?
// so something like
context.Response.Redirect(@"http://www.myRedirect.org");
// but as I said that doesn't redirect as I want it to be
}
}
Any ideas about that?
EDIT:
I tried the example, so I have:
private void OnBeginRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpContext context = app.Context;
// make a frame redirect if a specified page is called
if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html"))
{
// perform the frame redirect here, but how?
context.Response.Write(@"<html>");
context.Response.Write(@"<head>");
context.Response.Write(@"</head>");
context.Response.Write(@"<frameset rows=""100%,*"" framespacing=""0"" frameborder=""NO"" border=""0"">");
context.Response.Write(@"<frame src=""http://www.myRedirect.org"" scrolling=""auto"">");
context.Response.Write(@"</frameset>");
context.Response.Write(@"<noframes>");
context.Response.Write(@"<body>Some text...");
context.Response.Write(@"</body>");
context.Response.Write(@"</noframes>");
context.Response.Write(@"</html>");
}
}
But that also doesn't correctly redirect. I still have the redirect address shown in my browser. So any other idea?
EDIT:
I obviously made a mistake. The code above works and does what I want. It first didn't work because my redirect url was doing something unexpected.

要执行 框架重定向，您需要发回包含框架集的 HTML 代码单帧，其源设置为 http://www.myRedirect.org。就服务器和浏览器而言，没有发生重定向——它只是收到了一些 HTML 代码。
正如您所观察到的，执行 Response.Redirect 将会导致浏览器向新页面发出新的请求，并在标题栏中向用户显示新地址。它通常用于页面实际更改其地址，但所有者仍然希望可以从原始 URL 访问该页面的情况。
编辑：HTML框架重定向示例：http://en.wikipedia。 org/wiki/URL_redirection#Frame_redirects
To perform a frame redirect you need to send back the HTML code containing a frameset with a single frame, with it's source set to http://www.myRedirect.org. As far as the server and browser is concerned no redirect has happened - it's just received some HTML code.
Performing a
Response.Redirectwill, as you've observed, cause the browser to make a fresh new request to the new page, showing the user the new address in the title bar. It's typically used for when a page actually changes its address, but the owners still want it reachable from the original URL as well.EDIT: HTML frame redirect sample: http://en.wikipedia.org/wiki/URL_redirection#Frame_redirects
