1. An application in LAN area may exchange information in the following manner. GXP21xx sends
request and accepts XML contents via HTTP/HTTPS, directly communicating with the server. The
server will then handle the request and response via any protocols with the other application server to
get the expected information for the XML service.
2. If the above Web Server accesses Internet, it could interact with outside web server and respond
real-time content to GXP21xx.
As illustrated above, all of the application logic lies within the server side of the architecture. This allows
faster applications development and minimal phone side maintenance.
