| Default implementation of a strategy deciding about connection re-use.
The default implementation first checks some basics, for example
whether the connection is still open or whether the end of the
request entity can be determined without closing the connection.
If these checks pass, the tokens in the "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.
