304响应不设置自定义页眉与mod

本文介绍了304响应不设置自定义页眉与mod_headers中的Apache的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 <VirtualHost *:80> ServerAdmin webmaster@dev.dom DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" ServerName dev.dom ServerAlias dev.dom ErrorLog "logs/dev.dom-error.log" CustomLog "logs/dev.dom-access.log" common PassEnv CLUSTER Header always set X-Cluster "%{CLUSTER}e" </VirtualHost>

下面是我的配置。我有一个环境变量，它告诉我，我是什么群集上，这是在X-集群的标题传递。这将返回罚款200或404的响应，但304未修改响应永远不会返回头，虽然它返回其他相应的Apache头。

Here is my configuration. I have an environment variable which tells me what cluster I am on, which is passed as a header in 'X-Cluster'. This returns fine on a 200 or a 404 response, but a 304 Not Modified response never returns the header, even though it returns other appropriate Apache headers.

我如何获得的头一个304响应期间设置？

How do I get the header to be set during a 304 response?

推荐答案

阿帕奇明确禁止修改响应头为符合HTTP规范一个304响应。这种类型的响应的名称为未改性。您可以使用Apache的滤波器结构，修改此行为通过编写自定义的模块，或者与可能的mod_perl，但它是最有可能的错误的做法。

Apache explicitly prohibits modifying the response headers in a 304 response for compliance with the http spec. The name of this type of response is "Not modified". You can modify this behavior using Apache's filter architecture, by writing a custom module, or with mod_perl perhaps, but it's most likely the wrong thing to do.
