我有我的缓存相关的头设置中的8小时到期如下...我的Pragma HTTP响应头文件应该设置为?
header('Cache-Control: max-age=28800');
header('Expires:' . gmdate('D, d M Y H:i:s T', strtotime('+8 hours')));
有了这样的情况下,我应该我的语用HTTP响应头被设置为?

您不必设置杂注,仅当您需要no-cache指令时才设置杂注。在此处查看更多信息:http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32
请参阅PHP文档session_cache_limiter。您将看到正确的缓存头派:
市民:
Expires: (sometime in the future, according session.cache_expire)
Cache-Control: public, max-age=(sometime in the future, according to session.cache_expire)
Last-Modified: (the timestamp of when the session was last saved)
private_no_expire:
Cache-Control: private, max-age=(session.cache_expire in the future), pre-check=(session.cache_expire in the future)
Last-Modified: (the timestamp of when the session was last saved)
私人:
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: private, max-age=(session.cache_expire in the future), pre-check=(session.cache_expire in the future)
Last-Modified: (the timestamp of when the session was last saved)
非缓存:
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
我的服务器自动将Pragma设置为no-cache(我无权修改)。所以我想将附注值更改为与上面概述的缓存设置更一致的内容,或者通过我的PHP脚本以某种方式将整个编译指示字段清空。有任何想法吗? – Drew2345 2010-09-29 14:19:46
如果它是apache,它将.htaccess考虑在内,并有头文件模块,你可以使用这个指令“头文件unset Pragma” – hellvinz 2010-09-29 14:30:38
我不认为mod_headers.c被激活。 – Drew2345 2010-09-29 14:44:12
