windows-server-2003 – 如何在IIS 6中允许HTTP OPTIONS请求？

在http标头选项卡下有以下内容：

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST,deletE,OPTIONS
Access-Control-Allow-Headers: x-requested-with,cache-control,content-type,origin

在“主目录”选项卡下,为“仅脚本或脚本和可执行文件”设置“执行权限”.

我已完成所有这些,但当我尝试提交以下请求时,我收到403.1错误：

有没有人看到我配置IIS的方式有什么问题可能会导致此错误？
