Thank you Vasile,

Pls check out my code . What i need to do is , establish a connection to a
url using HttpClient and if there is some connection problems untill a time
out value , then HttpClient should close the connection.

This is my code snippet

      HttpParams httpParams = new BasicHttpParams();
      HttpProtocolParams.setVersion(httpParams, HttpVersion.HTTP_1_1);

      // set request params
      httpParams.setParameter("http.language.Accept-Language", "en-us");
      httpParams.setParameter("http.protocol.content-charset", "UTF-8");
      httpParams.setParameter("Accept",
"application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
      httpParams.setParameter("http.connection.stalecheck", false); // turn
off stale check checking for performance reasons


      SchemeRegistry schemeRegistry = new SchemeRegistry();
      schemeRegistry.register(new Scheme("http", 80,
PlainSocketFactory.getSocketFactory()));
      schemeRegistry.register(new Scheme("https", 443,
SSLSocketFactory.getSocketFactory()));

      final ThreadSafeClientConnManager cm = new
ThreadSafeClientConnManager(schemeRegistry);
      httpClient = new DefaultHttpClient(cm, httpParams);

      HttpConnectionParams.setConnectionTimeout(httpParams, 1000);
      HttpConnectionParams.setSoTimeout(httpParams, 10000);

      httpClient.getParams().setParameter("http.connection.timeout", 1000);
      httpClient.getParams().setParameter("http.tcp.nodelay", true);


and this is my log

Here DefaultHttpClient [DEBUG] Connection can be kept alive for 15000
MILLISECONDS . Is this default time out ???

Thank You,
