6.4.3 XTPro Web Browser-Based Implementation
A representative implementation based upon using a web browser as the client is detailed in Figure 35.
In this scenario, the client application is developed by using an active web server authoring tool (such as
Adobe Flash®). The active content is then embedded into one or more HTML files and loaded onto the
device’s file system (refer to section 6.4.1 for detailed information regarding customization of the web
server content). Accessing the device’s web server via a standard web browser then loads the active
content, which initiates communication with the server.
