I have an JSF page that redirects via context.getExternalContext().redirect(url); where the url is sth. like login.jsf?token=foobar
What I want now is to send the token via POST not via GET request. So that it doesn´t show up in the url, is this possible with JSF?
It’s not possible with HTTP, so also not with JSF. There are however several ways to achieve the requirement.
Put it in the session scope. In the bean behind the redirected page, read and remove it from the session scope. Or when you’re using JSF 2.0, use the flash scope.
Forward to a page containing a POST form pointing to the desired URL, having the token as hidden input value and include some JS code which does
form.submit()on page load.
