Hi There,


I am new to HtmlUnit and I am using this library to login/geo login with postcodes to different websites. I am able to login to websites but it is taking way too long(up to 5 mins). I need to have Javascript enabled to download the forms asyncronously. 

I am using below webclient configuration

        WebClient webClient = new WebClient(BrowserVersion.CHROME);

        WebClientOptions webClientOption = webClient.getOptions();
        webClientOption.setCssEnabled(false);
        webClientOption.setJavaScriptEnabled(true);
        webClientOption.setUseInsecureSSL(true);
        webClientOption.setTimeout(30000);
        webClientOption.setThrowExceptionOnScriptError(false);
        webClientOption.setThrowExceptionOnFailingStatusCode(false);
        webClientOption.setUseInsecureSSL(true);
        webClientOption.setActiveXNative(true);
        webClientOption.setAppletEnabled(true);
        webClientOption.setPopupBlockerEnabled(false);
        webClientOption.setRedirectEnabled(true);

        webClient.waitForBackgroundJavaScript(30000);
        webClient.waitForBackgroundJavaScriptStartingBefore(10000);
        webClient.setJavaScriptTimeout(30000);
        webClient.getCookieManager().setCookiesEnabled(true);
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());

          JavaScriptEngine scriptEngine = (JavaScriptEngine) webClient.getJavaScriptEngine();
        HtmlUnitContextFactory factory = scriptEngine.getContextFactory();
        Context context = factory.enterContext();
        context.setOptimizationLevel(9);
        
       
       
       This is happening with almost all the website I am trying to login. Any help in improving the time to run javascript will be greatly appreciated.
       
       
       
       Regards,
       Abhishek Thakur
