A downside to the use of server-side scripting is that the client needs to make further requests over the network to the server in order to show new information to the user via the web browser.
When the server serves data in a commonly used manner, for example, according to the HTTP or FTP protocols, users may have their choice of a number of client programs (most modern web browsers can request and receive data using both of those protocols).
In the case of more specialized applications, programmers may write their own server, client, and communications protocol, that can only be used with one another.
[1][2] Server-side scripting was later used in early 1996 by Fred Dufresne while developing the first website for Boston, MA television station WCVB.
In 2010, OIN named Fred DuFresne a "Distinguished Inventor" for his work on server-side scripting.
Those scripts were executed by the operating system, and the results were served back by the web server.
When using dynamic web-based scripting techniques, developers must have a keen understanding of the logical, temporal, and physical separation between the client and the server.
