# Alternative Agent Protocol

In environments when agents are behind a load balancer or reverse proxy which does a SSL offloading, the request URL is changed to match the URL that the agent receives.

The agent then uses the new URL as the redirection value in the pre-authentication cookie, created during the first unauthenticated request to the agent.

Use the following properties to override the agent redirection value with the URL of the original client request: [Alternative Agent Host Name](org.forgerock.agents.agent.hostname.html), and [Alternative Agent Port Number](org.forgerock.agents.agent.port.html).
