35.18.4 System architecture
XML applications may be hosted by one or more web servers used as proxy for other applications or
for internet web servers.
35.18.4.1 Internal application
The diagram below gives a detailed description of the architecture that allows an Aastra SIP terminal
to access an internal application. The application hosted by the web server translates requests from
the terminal into a protocol specific to the target application and formats the reply into an XML object
to be displayed on the terminal.
35.18.4.2 Internet application
The diagram below gives a detailed description of an XML application which attempts to retrieve
Internet data like, for example, a service used at the stock market to display stock values in real time.
Note: for some non-real-time web applications, the Internet content may be stored in cache memory
on the XML web server for quicker access.
