我有我的緩存相關的頭設置中的8小時到期如下...我的Pragma HTTP響應頭文件應該設置爲?
header('Cache-Control: max-age=28800');
header('Expires:' . gmdate('D, d M Y H:i:s T', strtotime('+8 hours')));
有了這樣的情況下,我應該我的語用HTTP響應頭被設置爲?

您不必設置雜注,僅當您需要no-cache指令時才設置雜注。在此處查看更多信息:http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32
請參閱PHP文檔session_cache_limiter。您將看到正確的緩存頭派:
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)
非緩存:
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
我的服務器自動將Pragma設置爲no-cache(我無權修改)。所以我想將附註值更改爲與上面概述的緩存設置更一致的內容,或者通過我的PHP腳本以某種方式將整個編譯指示字段清空。有任何想法嗎? – Drew2345 2010-09-29 14:19:46
如果它是apache,它將.htaccess考慮在內,並有頭文件模塊,你可以使用這個指令「頭文件unset Pragma」 – hellvinz 2010-09-29 14:30:38
我不認爲mod_headers.c被激活。 – Drew2345 2010-09-29 14:44:12
