Common to all three above:
Common Gateway Interface (CGI) was created as one way for Web servers to achieve a dynamic element by calling to programs that reside on the
server. This dynamic element allows the Web server to immediately respond to the request without doing additional processing. The server receives a
request from the browser, and it uses the dynamic element, or hypertext link, to connect with a new process. The server then passes CGI based tagged data
that will be used by the program to create, for example, the HTML file. The CGI program executes the associated display format subroutine, or script file,
and accesses other data sources to generate the content and then returns the HTML back to the HTTP server. Once the transfer is completed, the CGI
process terminates and the server transfers the HTML back to the requesting browser.
An alternative to using separate CGI scripts to define content is a template-based HTML that actually embeds a request for the dynamic data within the
HTML file itself When a specific page is requested, a pre-processor scans the file for proprietary tags that are then translated into final HTML based on the
request. The final HTML is then passed back to the server and on to the browser for the user to view on their computer terminal. While the examples given
have been explained in the context of HTML, both CGIs and templates may be created with any Standard Generalized Markup Language (SGML) based
markup language, such as Handheld Device Markup language (HDML). HDMI, is a markup language designed and developed by AT&T and Unwired
Planet, Inc. to allow handheld devices some access to the resources of the Internet. The specifics of the language are disclosed in "HDML Language
Reference, Version 1.0," Unwired Planet, Inc., Jul. 1996, and herein incorporated by reference. |
