我试图通过ashx页面将flv文件加载到JWPlayer中。但我总是得到以下错误：JW Player无法显示通过文件处理程序（.ashx）提供的flv
Task Queue failed at step 5: Playlist could not be loaded: Playlist file did not contain a valid playlist
如果我直接在Firefox中加载ashx页面，视频将加载并自动播放。如果我改变flvplayer直接指向一个flv文件，它工作正常。所以我对这个问题有些困惑！我注意到的一件事是，直接通过浏览器播放时，ashx页面后面的代码运行两次，第二次没有会话变量可用，尽管Fiddler只能检测到浏览器的一个请求。当JWPlayer调用ashx页面时，代码只执行一次。
任何帮助，将不胜感激！
