URLs with spaces fail because spaces are sent to the server unencoded

[dreamlayers]

I tried to play an MP3 file on an http server via the web interface. The filename contained spaces. That failed because the space was sent as-is to the server, and that is not allowed. The result was a "400 Bad Request" error. Then I tried doing the URL encoding myself, replacing spaces with %20. That still failed. The %20 got decoded into a space somewhere, and that space was sent to the server.

Finally, I URL encoded the %20, replacing spaces with %25%32%30. That worked, sending %20 for spaces in the filename. The file played back successfuly.
