是否有一种方法可以禁用单个页面的浏览器缓存?

For a small intranet site, I have a dynamic (includes AJAX) page that is being cached incorrectly by Firefox. Is there a way to disable browser caching for a single page?

对于一个小型的内部网站点，我有一个动态(包括AJAX)页面被Firefox错误地缓存。是否有一种方法可以禁用单个页面的浏览器缓存?

Here's the setup I'm using:

下面是我使用的设置:

Apache under XAMPP, running on a Windows server
在XAMPP下运行的Apache
PHP
PHP

Clarification

The content that I'm primarily concerned about is page text and the default options in some <select>s. So I can't just add random numbers to the end of some image URLs, for example.

我主要关心的内容是页面文本和一些

Update:

I followed the suggestions I've gotten so far:

我遵循了我到目前为止得到的建议:

I'm sending nocache headers (see below)
我将发送nocache标题(见下面)
I'm including a timestamp URL parameter and redirecting to a new one if the page is reloaded after 2 seconds, like this:

我将包含一个时间戳URL参数，如果页面在2秒后重新加载，则将重定向到一个新参数，如下所示:
```
$timestamp = $_GET['timestamp'];
if ((time()-$timestamp) > 2) {
    header('Location:/intranet/admin/manage_skus.php?timestamp='.time());
}
```

Now Firebug shows that the headers specify no cache, but the problem persists. Here are the response headers for the page:

现在，Firebug显示header没有指定缓存，但是问题仍然存在。以下是该页面的响应头:

Date    Fri, 25 Sep 2009 20:41:43 GMT

6 个解决方案

#1

Add current timestamp as parameter of url, e.g.

添加当前时间戳作为url的参数，例如。

http://server.com/index.php?timestamp=125656789

I think this tells you what you want:

Look for "Preventing the Browser From Caching"

寻找“阻止浏览器缓存”

header( "Expires: Mon, 20 Dec 1998 01:00:00 GMT" );
header( "Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );
header( "Cache-Control: no-cache, must-revalidate" );
header( "Pragma: no-cache" );

#3

You should send the following header:

你应该发送以下标题:

Cache-control: no-cache

in the HTTP response.

在HTTP响应。

#4

You could add these headers:

您可以添加以下标题:

Cache-Control: no-cache

And (for backward compatibility with HTTP/1.0 clients)

和(用于与HTTP/1.0客户端向后兼容)

Pragma: no-cache

#5

Here's another take that isn't PHP specific.

这里还有另外一个不是PHP特有的。

Try this in your <head> </head> section:

在你的 section:

<meta http-equiv="cache-control" content="no-cache, no store"/>
<meta http-equiv="Expires" Content="Mon, 25 May 2009 19:07:03 GMT">

Found that at the end of a long thread here:

Use the header() function. You have to set a few to cover all browsers; see http://www.php.net/manual/en/function.header.php#75507

使用header()函数。你必须设置一些来覆盖所有浏览器;见http://www.php.net/manual/en/function.header.php # 75507
