推荐答案

Webcal 最初用于 Apple iCal 应用程序，并已成为通过 WebDAV 访问 iCalendar 格式文件的通用事实上的标准.[需要引用] 它不是官方 URI 方案，例如 http: 和 ftp:，如在 IANA 注册.Webcal 协议前缀用于触发外部协议处理程序，该处理程序传递 .ics 文件的 URL 而不是传递文件的下载内容，与 feed: 有时用于触发外部 RSS 阅读器的方式大致相同.这个想法是，使用这个协议前缀，目标文件应该被订阅，而不是像简单的下载那样导入到日历应用程序中.

Webcal was initiated for use with the Apple iCal application and has become a common de facto standard for accessing iCalendar formatted files via WebDAV.[citation needed] It is not an official URI scheme, such as http: and ftp:, as registered with IANA. The Webcal protocol prefix is used to trigger an external protocol handler which is passed the URL of the .ics file rather than being passed the downloaded contents of the file, in much the same way feed: is sometimes used to trigger external RSS readers. The idea is that with this protocol prefix the target file should be subscribed to rather than imported into the calendar application as would happen with a simple download.
