状态码

206

206是部分内容的状态码。下载视频的时候首次观察到:

$ wget -c 'http://60.5.254.18/flv.vodfile.m1905.com/201111282049/a3981c94640b109b4906e6812ec84fb5/movie/guSqlfsSJeTTS45m.flv'

这是因为下载前这个文件已经有了一点,wget进行了续传,发送的请求Header里面指定了Range,151M就是要下载的部分。服务端必须支持续传才行。

虽然服务器说文件大小是169M(177083638),但得到的文件实际大小是178MiB(186786856 B):

-rw-rw-r--   1 tux tux 186786856 2011-08-10 13:30 guSqlfsSJeTTS45m.flv

可能是服务端的设置有问题。
