Examples of org.apache.http.nio.protocol.ThrottlingHttpServiceHandler

org.apache.http.nio.protocol.ThrottlingHttpServiceHandler
HTTP service handler implementation that allocates content buffers of limited size upon initialization and is capable of controlling the frequency of I/O events in order to guarantee those content buffers do not ever get overflown. This helps ensure near constant memory footprint of HTTP connections and to avoid the 'out of memory' condition while streaming out response content.
The service handler will delegate the task of processing requests and generating response content to an {@link Executor}, which is expected to perform those tasks using dedicated worker threads in order to avoid blocking the I/O thread.
