Abstract
A preprocessing script-based data communications system and method that embeds information regarding the previous state of the system within script data. This effectively imposes a state memory upon what would otherwise be a stateless system. Typically, the scripts processed by this system are similar in structure and format to ordinary HTML scripts, with the addition of several commands that facilitate programming embedded state information. Within systems employing the invention a client is afforded the capability of having one script influence another by exploiting the preprocessor imposed state memory. In addition, the invention provides these advantages to a client without the need for storing state information on a data system server, thereby providing increased system security.
