Interactive Multiuser Web Applications

FlashCONNECT Administrator’s Guide 17

Clicking a browser link sends a message to the server. The server responds by

sending the document. Once the browser receives the entire document, the server

no longer tracks the session.

This works well for requesting a static page from the server; however, HTTP is not

sufficient to program a multiuser interactive application. For example, consider an

interactive customer update application. The server must be able to store the

current state of the progressing transaction between data transfers. The server, like

any application, must not allow other users to update records that are currently

locked. HTTP cannot accomplish this task by itself.

FlashCONNECT Solution

FlashCONNECT resolves this session tracking problem by keeping track of the

application state. See the FlashCONNECT session tracking solution illustrated below.
