Class org.apache.http.ConnectionReuseStrategy

Examples of org.apache.http.ConnectionReuseStrategy.keepAlive()

org.apache.http.ConnectionReuseStrategy.keepAlive()
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. @param response The last response received over that connection. @param context the context in which the connection is being used. @return true if the connection is allowed to be reused, orfalse if it MUST NOT be reused
