将http请求中的keep alive标头设置为false

Question

I have limit of maximum two concurrent login from a user in application. I want to terminate the session after the soap webservice request but my session is not terminating. I have tried different ways but did not get any success.

How should I set the keep alive header so that after the web service call the session get end.

public class CallDropIncidentDataClient {
    private static com.hp.schemas.sm._7.CallDropIncidentManagement getPaymentServicePort() {
        URL url = null;

        } catch (MalformedURLException ex) {

Answer 1

Try adding header like this addHeader("Keep-Alive", "timeout=60000")

Refer this post here

Also check in documentation the possible standard values of Keep-Alive here
