Interface for deciding whether a connection should be kept alive.
(HttpResponse response, HttpContext context)
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.
||The last response received over that connection.
||the context in which the connection is being
true if the connection is allowed to be reused, or
false if it MUST NOT be reused
