Dynamic pages - server-side

Dynamic pages: Page is built by a program (rather than static pre-built page).

Where should the program to build the page be run? On the server or client? Or both?

When should the program run on the server?
Basically: If it has to run on the server. Can't run on client.
e.g. Interact with server database.

Generic server-side scripting

CGI (Common Gateway Interface) is the oldest way of putting a program on the server side.

• CGI scripts
• It is language independent. Any program in a special directory (normally cgi-bin) can be addressed over the Web.
• Can put any program at all on the Internet.
• It is less used now. Dedicated server-side solutions integrated with the web server (like PHP) are preferred, rather than just a directory of standalone programs.
