在使用母版页的ASP.NET页面上禁用浏览器缓存 [英] Disabling Browser Cache on ASP.NET Pages That Use Master Pages
问题描述
我正在编写一个使用母版页的ASP.NET 2.0应用程序。我有一些
页面，不能在客户端上缓存。在ASP.NET 1.1中，我使用元标记实现了这个
：
< meta http-equiv =" Expires" content =" 0">
< meta http-equiv =" Pragma" content =" no-cache"
< meta http-equiv =" Cache-Control" content =" no-cache">
此标记是< headelement的一部分。我看过的示例代码
显示了如何添加表单的元标记：
< meta name =" KEYWORDS" content =" html，webdesign，javascript">
文档和文献说使用Page_Load事件处理程序中的代码
如下：
base.Master.Page.Header.Metadata.Add（" Keywords"，" html，..."）;
但是当我尝试这个时，我得到一个编译错误，表明Header
没有Metadata属性。
如何以编程方式将所需的元标记添加到Master页面派生
aspx页面禁用客户端缓存？
一如既往，非常感谢任何指导。

I am writing an ASP.NET 2.0 application that uses master pages. I have some
pages that must not be cached on the client. In ASP.NET 1.1 I achieved this
using metatags:
<meta http-equiv="Expires" content="0">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">
This tags are part of the <headelement. Sample code that I have seen
shows how to add metatags of the form:
<meta name="KEYWORDS" content="html, webdesign, javascript">
Documentation and literature says to use code in the Page_Load event handler
as follows:
base.Master.Page.Header.Metadata.Add("Keywords", "html,...");
However when I attempt this I get a compile error indicating that Header
does not have a Metadata property.
How can I programmatically add the needed metatags to an Master page derived
aspx page to disable client-side caching?
As always, any guidance is greatly appreciated.

您可以在2.0中执行相同操作，或者确实在任何基于HTML的环境中执行相同操作
这是一个HTML问题，无关使用服务器端环境。
You can do the same in 2.0, or indeed in any HTML-based environment as
this is an HTML issue, nothing to do with the server-side environment.

在< headin主页面内添加contentplaceholder。然后在
中需要这些标题的任何页面，用
这些元标记填充内容控件。其他页面不需要填充（甚至没有）
内容控件。
我这么做很多，而且更容易（和更少的代码）比
神秘消失的base.Master.Page.Header.MetaData.Add（）方法，
让我感到非常苛刻在第一个
的地方做到这一点。

（此行以下添加的任何内容都与我无关）
Add a contentplaceholder inside the <headin your master page. Then in
any pages that need these headers, populate the content control with
these meta tags. Other pages don''t need to populate (or even have) the
content control.
I do this a lot and it''s much easier (and less code) than the
mysteriously vanishing base.Master.Page.Header.MetaData.Add() method,
which struck me as being a very heavy-handed way to do it in the first
place.

我更喜欢使用：
Response.Cache.SetNoStore（）;
....而不是使用元标记。

实际上做了什么？它是否会发送额外的标题，或只是为了给你编写元标记
？之前没有碰到它。
无论哪种方式，我的观点是将元标记写入内容控件
通常比使用Metadata.Add容易得多方法。你的方法
对于这个特殊问题更容易。

What does that actually do? Does it send extra headers, or does it just
write meta tags for you? Not come across it before.
Either way, my point was that writing meta tags into a content control
is generally much easier than using the Metadata.Add method. Your method
is even easier for this particular issue.
