发送304时的Apache忽略PHP头 [英] Apache ignoring PHP headers when sending a 304
问题描述
在我的Apache + mod_php5设置自定义标题，这工作得很好：
When I set a custom header in Apache + mod_php5, this works fine:
header('Foo: Bar');
但是，当我尝试这个的，而的同时送一个304未修改响应，头部似乎被Apache删除（一起通过X供电，通过和其他标准的头）。
But when I try this while also sending a 304 Not Modified response, the header appears to be removed by apache (along with X-Powered-By and other standard headers).
header('HTTP/1.1 304 No Content');
header('Foo: Bar');
有谁知道如何解决这个问题呢？
Does anyone know how to solve this issue?
推荐答案
这难道不是回答这个问题？
Does this not answer the question?
如果有条件的习惯强大的缓存验证（见13.3.3），响应不应该包含其他实体头。否则（即，有条件的习惯弱验证），响应必须不包括其他实体头;缓存的实体机构和更新头之间的prevents不一致。
If the conditional GET used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. Otherwise (i.e., the conditional GET used a weak validator), the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers.
