The Open Client Runtime provides several properties that determine the behavior of the client application. These properties are called proxy properties. You can specify proxy properties default behavior with an application configuration file and/or by calling methods on the OpenEdge-provided classes, com.progress.open4gl.RunTimeProperties and com.progress.open4gl.javaproxy.Connection.

There are several properties that govern behavior across an entire application. These properties do not affect any particular object, but they affect the behavior of all objects created by the application. They are referred to as proxy run-time properties.

Other properties govern behavior across a single application service. These properties are called proxy connection properties.
