Gets or sets a value indicating whether the server requests a persistent connection.
Assembly: System (in System.dll)
If an HTTP client and server expect to exchange data multiple times in a short period, a persistent connection speeds up their communications by allowing them to avoid the overhead required to open and close a TCP connection for each message. Persistent connections are in widespread use in communications between modern Web browsers and Web servers.
Persistent connections are described in detail in the HTTP/1.1 protocol specification (RFC 2616) available at the RTF Editor Web site (http://www.rfc-editor.org).
