Yes, you should use 1 instance of HttpClient and make sure you are using the MultiThreadedHttpConnectionManager. So something like: HttpClient client = new HttpClient(new MultiThreadedHttpConnectionManager()); PostMethod login = new PostMethod(...); client.execute(login); login.releaseConnection(); Create as many threads as you like to do something like: GetMethod get = new GetMethod(...); client.execute(get); get.releaseConnection(); You should probably take a look at the multithreading guide: http://jakarta.apache.org/commons/httpclient/threading.html > 2.

On this I couldn't be entirely certain and don't have time to analyse the code right now, though you could certainly do it yourself or even easier, just test it and find out. :) > Yue Regards, Adrian Sutton. ---------------------------------------------- Intencha "tomorrow's technology today" Ph: 38478913 0422236329 Suite 8/29 Oatland Crescent Holland Park West 4121 Australia QLD www.intencha.com --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
