This is disabled, because otherwise VLC needs to Seek back to the index of the file on the webserver, causing a lot of HTTP requests to be going around between server and client. It was considered by servers to be highly annoying. In the future we likely "remember" the index in some sort of way, but it's not finished yet.
Many thanks for a prompt reply.
Whether It is impossible to make in the future versions the hidden option allowing to bypass this restriction?
For my server such loading is not critical and absence of rewind extremely inconveniently.
It is necessary to use MPlayer in some cases.: (((
