By default this is done to keep the resource consumption low when the
server is very heavily loaded. To increase the duration the Poller can
remain active you must configure a PipelineHandler like so.

ProtocolHandler server = new MyProtocolHandler();
PipelineHandler handler = PipelineHandlerFactory.getInstance(server, 10,
5000);
Connection con  = ConnectionFactory.getConnection(handler);

In the above statement I am creating a PipelineHandler that uses 10
Poller objects to poll incoming connections, these Pollers will be idle
for no longer than 5 seconds. By default a Poller will only ever be idle
for 1 second. 

One thing to note is that if you set the maximum idle time for Poller
objects to 5 seconds or more you will experience a noticeable delay
before a response is sent by the server, this is because the Poller
responsible for the connection may be in a wait queue for up to the
maximum idle time, regardless of the load on the server.

An alternative, which I use when using HTTP Basic Authentication and SSL
is to use a special Poller implementation called the GranularPoller. You
must have Simple 2.4.2 or above. To use this poller the system property
simple.http.poller must be set to simple.http.GranularPoller, try this:


java -Dsimple.http.poller=simple.http.GranularPoller 


With this you will not need to create a custom PipelineHandler as this
will perform a much larger number of poll iterations.

Hope this helps,
