WebGate is an access client for enforcing access policies on HTTP-based resources. The WebGate client runs as a plugin that intercepts HTTP requests for web resources and forwards them to the access server where access control policies are applied. You must configure it on the same Oracle HTTP Server on which you have installed your product instances. WebGate is automatically bundled with Oracle HTTP Server 12c.
To configure Oracle HTTP Server 12c, see the Configuring Oracle HTTP Server 12c WebGate section of the Oracle Fusion Middleware Installing and Configuring Oracle HTTP Server.
After your WebGate has been configured with an Oracle HTTP Server, you must register your WebGate with Oracle Access Manager by using the Oracle Access Manager Administration Console.
To register your WebGate with Oracle Access Manager, see the Registering and Managing OSSO Agents Using the Console section of the Fusion Middleware Administrator's Guide for Oracle Access Manager with Oracle Security Token Service guide.
