Class Overview
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.

Public Methods
Decides whether a connection can be kept open after a request.
If this method returns false
, the caller MUST
close the connection to correctly implement the HTTP protocol.
If it returns true
, the caller SHOULD attempt to
keep the connection open for reuse with another request.
One can use the HTTP context to retrieve additional objects that
may be relevant for the keep-alive strategy: the actual HTTP
connection, the original HTTP request, target host if known,
number of times the connection has been reused already and so on.
If the connection is already closed, false
is returned.
The stale connection check MUST NOT be triggered by a
connection reuse strategy.
Parameters
response
| The last response received over that connection. |
context
| the context in which the connection is being
used. |
Returns
true
if the connection is allowed to be reused, or
false
if it MUST NOT be reused
Protected Methods
Creates a token iterator from a header iterator.
This method can be overridden to replace the implementation of
the token iterator.
