php - 头文件('P3P: CP=“CAO PSA OUR”');做？

header('P3P: CP="CAO PSA OUR"');是做什么用的？

如何/为什么要让此脚本在IE中正常工作？

session_start();

if (!session_is_registered(pre_myusername)) {
    header("location:index.php");
    exit();
}

最佳答案

P3P is the Platform for Privacy Preferences.值CP="CAO PSA OUR"用 token 描述了compact policy

contact and others (access information: What information is collected?)

pseudo-analysis (purpose information: What is the collected information used for?)

ours (receipient information: Who gets that collected information?)
