Oggetto: Re: PoolingClientConnectionManager set max number of requests
Thanks Oleg, it works like a charm ;) !
Only one thing, I set 2 max connections for my pooledConnetion like this
int maxConnection = 2;
cm = new PoolingClientConnectionManager(schemeRegistry);
cm.setMaxTotal(maxConnection);
cm.setDefaultMaxPerRoute(maxConnection);
HttpHost localhost = new HttpHost(urlServer, port);
cm.setMaxPerRoute(new HttpRoute(localhost), maxConnection);
and I aspect when call in multithread program
DefaultHttpClient ret = new DefaultHttpClient(cm);
that threads take the connection if one of two connection is not used but wait
until one connection is free, but debugging my code all thrad get HttpClient.
Is it possible to have a BlockingPool configuring same parameters or could you
give me some hints to do that ?
Thanks you very much

Custom connection re-use strategy and connection metrics are your
friends
---
DefaultHttpClient client = new DefaultHttpClient();
client.setReuseStrategy(new DefaultConnectionReuseStrategy() {
@Override
public boolean keepAlive(HttpResponse response, HttpContext context)
{
boolean result = super.keepAlive(response, context);
if (result) {
HttpConnection conn = (HttpConnection) context.getAttribute(
ExecutionContext.HTTP_CONNECTION);
HttpConnectionMetrics metrics = conn.getMetrics();
if (metrics.getRequestCount() > 0) {
return false;
}
}
return result;
}
});
