@Immutable public class DefaultConnectionReuseStrategy extends Object implements ConnectionReuseStrategy
Connection
header will
be examined. In the absence of a Connection
header, the
non-standard but commonly used Proxy-Connection
header takes
it's role. A token close
indicates that the connection cannot
be reused. If there is no such token, a token keep-alive
indicates that the connection should be re-used. If neither token is found,
or if there are no Connection
headers, the default policy for
the HTTP version is applied. Since HTTP/1.1
, connections are
re-used by default. Up until HTTP/1.0
, connections are not
re-used by default.Modifier and Type | Field and Description |
