This allows adding web proxies to the list.

Attribute	Description

This allows specifying a set of shared properties that should be consumed on system start. Although changes to shared properties is allowed using editor in System Console app, when a property needs to be effected at system start, use this section. The properties specified here are consumed at system initialization and updated in database.
