IIS 7.5如何添加动态HTTP过期标头 [英] IIS 7.5 How do you add a Dynamic HTTP Expires Header
问题描述
在IIS 7.5中,您可以添加静态HTTP响应标头,但我想添加一个Expires标头,该标头始终指定将来7天的日期。
In IIS 7.5, you can add static HTTP Response headers, but I want to add an "Expires" header that always specifies a date that is 7 days in the future.
我正在运行php 5.4,所以我想要一个可以通过编辑web.config文件而不是一些c#代码解决方案来做到这一点的解决方案。
I'm running php 5.4, so I'd like a solution that can do this by editing the web.config file rather than some c# code solution.
我知道如何使用php添加标题,但这对静态图像文件的http标头(jpg,gif,png等)没有帮助。
I know how to add the header using php, but that won't help for static image file's http headers (jpg, gif, png, etc).
标题应该看起来像这样:
The header should look something like this:
到期:星期四,2012年5月31日10:59:25 GMT
Expires: Thu, 31 May 2012 10:59:25 GMT
怎么能我动态地总是显示未来7天的日期和时间?
How can I make it dynamically always show a date and time 7 days in the future?
编辑:
请注意我在php文件中有我想要的expires头:
Notice that I have the expires header that I want on my php files:
http://web-sniffer.net/?url=http%3A%2F%2Fwww.bestds.com
但是,我无法指定7天的日期为png文件中的Expires键提前(例如),我将来必须使用静态日期:
However, I'm not able to specify a date that is 7 days ahead for the "Expires" key on png files (for example), I'm having to use a static date far in the future:
http://web-sniffer.net/?url= http%3A%2F%2Fwww.bestds.com%2Fimage%2Ftlogo.png
推荐答案
这是一个标准IIS的功能。 HTTP Response Headers模块允许您设置此公共标头。这导致以下web.config:
This is a standard feature of IIS. The HTTP Response Headers module allows you to set this common header. This results in the following web.config:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />
</staticContent>
</system.webServer>
</configuration>
您应该只在要发送此标头的目录中执行此操作。通常只有具有静态内容的目录。
You should do this only in the directories where you want this header to be send. Typically only directories with static content.
