- Server Side Programming can store and execute program on Web server, link from Web page
- more complex, requires server privileges, but can still be (mostly) secure
- Common Gateway Interface (CGI) programming
- programs can be written to conform to the CGI
- when a Web page submits, data from the page is sent as input to the CGI program
- CGI program executes on server, sends its results back to browser as a Web page
- good if computation is large/complex or requires access to private data
- see http://hoohoo.ncsa.uiuc.edu/cgi/
- Active Server Pages (ASP), Java Servlets, PHP, Server Side Includes, Ajax
- some of these are vendor-specific alternatives to CGI (such as ASP)
- provide many of the same capabilities but using HTML-like tags
- some of these technologies might require functionality to be enabled in the client’s browser (e.g. Ajax generally requires the use of Javascript)
