java - DefaultClient keep alive -

where issue ? when use same request , setup httpclient 3.1, persistent connection keep, no in httpclient 4.x [defaultclient].

javax.net.ssl.sslcontext ctx = javax.net.ssl.sslcontext.getinstance("tls"); ctx.init(keyfactory.getkeymanagers(), tmfactory.gettrustmanagers(), new    securerandom()); .. schemeregistry schemeregistry = new schemeregistry(); schemeregistry.register(new scheme("https", 443, new mysslfactory(ctx)));  poolingclientconnectionmanager cm = new poolingclientconnectionmanager(schemeregistry); cm.setmaxtotal(20); cm.setdefaultmaxperroute(5); cm.setmaxperroute(new httproute(localhost), 5); httpparams httpparameters = new basichttpparams(); httpconnectionparams.setconnectiontimeout(httpparameters, 5000); // connection timeout httpconnectionparams.setsotimeout(httpparameters, 0); httpclient client = new defaulthttpclient(cm,httpparameters);            while (i<200) {     httppost post = new httppost(send.geturl().tostring());     header[] heads =  post.getallheaders();     system.out.println("request headers size:"+heads.length);     (int ii=0; ii<heads.length; ii++) {         header head = heads[ii];         system.out.println("name:"+head.getname()+",  value:"+head.getvalue());      }            contenttype contenttype =     contenttype.create("text/xml","utf-8");            httpentity entity = new stringentity(data,contenttype );     post.setentity(entity);     httpresponse resp = client.execute(post); ... } client.getconnectionmanager().shutdown();
