I have a url like http://localhost:8020/stream.flv

On request to my php sctipt I want to return (be something like a proxy) all data I can get from that URL (so I mean my php code should get data from that url and give it to user) and my header and my beginning of file.

So I have my header and some data I want to write in the beginning of response like

# content headers
        header("Content-Type: video/x-flv");
        header("Content-Disposition: attachment; filename=\"" . $fileName . "\"");
        header("Content-Length: " . $fileSize);

        # FLV file format header
        if($seekPos != 0) 
        {
        print('FLV');
        print(pack('C', 1));
        print(pack('C', 1));
        print(pack('N', 9));
        print(pack('N', 9));
    }

How to do such thing?
