blocks|key|4641885|text|我不认为您可以从具有某种Page.IsInIFrame()类型的功能的意义上进行检测，但是您可以考虑为那些加载到IFrame中的页面和那些没有加载的页面提供不同的基类，这样您就可以知道错误来自于对IFrame页面的请求，这在一定程度上可能会有所帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4641886|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I don't think you can detect in the sense of having some sort of Page.IsInIFrame() kind of functionality, but you could consider having different base classes for those pages that are loaded in an IFrame and those that aren't so that you can know the error is from a request that was for an IFrame page that may help to some extent.

blocks|key|4641909|text|在服务器端是没有办法的。唯一的方法是通过javascript。在执行重定向时，可以通过querystring传递错误消息或代码吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4641910|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

There's no way from the server-side. The only way is via javascript. When you do the redirect, can you pass the error message or code via a querystring?

blocks|key|576833|text|在window.location中使用Javascript进行重定向不是很有效吗？强制执行全页重定向？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|576834|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Won't it work to redirect using Javascript with window.location? Forcing a full page redirect?

You can do it in client side: <a href="https://stackoverflow.com/questions/326069/how-to-identify-if-a-webpage-is-being-loaded-inside-an-iframe-or-directly-into-t">How to identify if a webpage is being loaded inside an iframe or directly into the browser window?</a>

The workaround i found is put some identifier into querystring of a url opened inside iframe.

blocks|key|3798078|text|这是不可能的，因为客户端可以在禁用javascript的情况下打开iframe。http://caniuse.com/#feat=iframe-sandbox|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3798079|entityMap|0|LINK|mutability|MUTABLE|url|http://caniuse.com/#feat=iframe-sandbox^0|14|13|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

This is impossible because client can open iframe with javascript disabled. <a href="http://caniuse.com/#feat=iframe-sandbox" rel="nofollow">http://caniuse.com/#feat=iframe-sandbox</a>

blocks|key|3798102|text|只需检查当前页面的url即可。如果与IFrame页面相同，则重定向到Default.aspx或其他任何页面。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3798103|Dim+urlpath1+As+String+=+HttpContext.Current.Request.Url.AbsoluteUri

simply, check the url of current page..
if it's the same with the IFrame page then redirect to Default.aspx or whatever.

<pre><code>Dim urlpath1 As String = HttpContext.Current.Request.Url.AbsoluteUri
If Right(urlpath1, 13) = "WebForm1.aspx" Then
 Response.Redirect("~/")
 Else
 Response.Write("It's OK!")
 End If
</code></pre>

Is it possible to determine - server-side - whether a page has been loaded within an <code>IFrame</code>?

When certain errors happen in my application the user gets redirected to <code>Default.aspx</code> and an error message is shown. The text of that error message gets set in session by exception handling code. The error message gets cleared from session once it has been shown.

However, part of my application has to use an <code>IFrame</code> (it's doing a 3D Secure card payment check, which mandates an <code>IFrame</code> in order to display the card provider's authentication UI). If an error takes place during this process my redirect takes effect within the <code>IFrame</code>. I am using JavaScript to detect this and reload <code>Default.aspx</code> correctly, but this means that I get two <code>Page_Loads</code> in rapid succession, and the error message only gets shown on the first one (and then cleared).
