As in htmlunit use cookies on the same site. I log in to the site, display the result as text. It is written that "the input is made successfully." I go to the main page of this site and it says there that I have not logged in (Log in, register, it is written).
I create a WebClient like this:

  final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_45); webClient.getOptions().setJavaScriptEnabled(true); webClient.getOptions().setRedirectEnabled(true); webClient.getOptions().setThrowExceptionOnScriptError(false); webClient.getOptions().setCssEnabled(false); webClient.getOptions().setUseInsecureSSL(true); webClient.getOptions().setThrowExceptionOnFailingStatusCode(false); webClient.getCache().setMaxSize(0); CookieManager cm = new CookieManager(); webClient.setCookieManager(cm);

Writes:
