# About server affinity providers

The PingDirectoryProxy server supports the ability to forward a sequence of requests to the same external server if specific conditions are met, called server affinity.

Use the server affinity provider to establish an affinity to a particular backend server for certain operations.

The following provider configurations and server affinity methods are available in the PingDirectoryProxy server:

* Client connection Server Affinity

  Requests from the same client connection consistently route to the same backend server.

* Client IP address Server Affinity

  All requests coming from the same client system consistently route to the same backend server.

* Bind DN Server Affinity

  All requests from the same user consistently route to the same backend server.

For information about configuring server affinity, see [Configuring server affinity](pd_proxy_config_server_affinity.html).
