On demand configuration (ODC) enables product components, such as the proxy server, to build application deployment, availability, and accessibility information to route requests for these applications without any additional configuration at the proxy server. If you want to isolate proxy servers with firewalls, place them in a cell that is separate from the applications, and configure the core group bridge service.
ODC uses the high availability capabilities of the product to publish and subscribe updates. The deployment manager within a cell and the application servers that have the ODC capabilities typically publish the updates that are subscribed to by intermediaries such as the proxy server.
You can configure the proxy server to route requests to applications that are hosted in other cells. The core group bridge service provides communication between a cell with a proxy server and a cell with a target application. After the cells are linked with core group bridges, the proxy server will route to the application without additional configuration. To view your core group bridge settings, in the administrative console, click
.The basic steps to configure cross-cell routing are configuring and enabling core group bridges in the cell that the proxy server belongs to, and in each of the other cells that are being routed to. The core group bridges need to be configured with the same access point group name.
