keepAlive
boolean keepAlive(HttpResponse response, HttpContext context)
Decides whether a connection can be kept open after a request. If this method returnsfalse
, the caller MUST close the connection to correctly comply with the HTTP protocol. If it returnstrue
, 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, orfalse
if it MUST NOT be reused
