回答如下:
【 在 ohcabinet 的大作中提到: 】
Flash Video content delivered using HTTP lacks intellectual property (IP) protection. There is no way to limit offline access to Flash Video content served over HTTP: The Web browser caches Flash Video files in its temporary storage, which can be accessed by the user after browsing the site. As such, content producers and licensees don't distribute Flash Video content over HTTP; RTMP is the preferred protocol.
answer from internet
讨论了使用HTTP传输的Flash视频内容如何容易被离线访问,并指出RTMP是更合适的传输协议来限制此类内容的离线访问。
