There are two ways to deliver video files over the web: (i) progressive download and (ii) streaming. Progressive downloads are typically cheaper and work with any server, but do not offer content protection nor seeking to undownloaded parts. Streaming servers (e.g. FMS, Wowza or Red5) offer these functionalities, but must be installed on your server(s). Since server side access and / or knowledge is not always readily available, some developers choose an “in between” solution of HTTP streaming through the use of a small server side script (e.g. PHP, ASP, etc.). This section will describe such methods.
