Disconnect from a REST Server

Demonstrates Rest.Disconnect, which closes the current HTTP connection. The argument is the maximum number of milliseconds to wait for the close to complete.

Background. Connections are normally kept alive for reuse. Disconnect is used when an application wants to explicitly release the connection rather than relying on keep-alive or object destruction.
