getKeepAliveDuration
public long getKeepAliveDuration(org.apache.http.HttpResponse response, org.apache.http.protocol.HttpContext context) Description copied from interface:ConnectionKeepAliveStrategy
Returns the duration of time which this connection can be safely kept idle. If the connection is left idle for longer than this period of time, it MUST not reused. A value of 0 or less may be returned to indicate that there is no suitable suggestion. When coupled with aConnectionReuseStrategy
, ifConnectionReuseStrategy.keepAlive(HttpResponse, HttpContext)
returns true, this allows you to control how long the reuse will last. If keepAlive returns false, this should have no meaningful impact- Specified by:
getKeepAliveDuration
in interfaceConnectionKeepAliveStrategy
- Parameters:
response
- The last response received over the connection.context
- the context in which the connection is being used.- Returns:
- the duration in ms for which it is safe to keep the connection idle, or <=0 if no suggested duration.
