public TimeValue getKeepAliveDuration(final HttpResponse response, final HttpContext context)

Implements org.apache.hc.client5.http.ConnectionKeepAliveStrategy.getKeepAliveDuration.

Doc from org.apache.hc.client5.http.ConnectionKeepAliveStrategy.getKeepAliveDuration.

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 a org.apache.hc.core5.http.ConnectionReuseStrategy, if org.apache.hc.core5.http.ConnectionReuseStrategy#keepAlive( org.apache.hc.core5.http.HttpRequest, 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

Parameters
response:HttpResponse

The last response received over the connection.

context:HttpContext

the context in which the connection is being used.

Returns:TimeValue

the duration in ms for which it is safe to keep the connection idle, or <=0 if no suggested duration.
