FlowScope get clear on page refresh

Based on my application requirements, I have to declare some variables for login process(say, failed login attempts).

hence, using

context.getFlowScope().put("count", ++count);

seems to be the solution. But after refreshing the page, using F5 or even in worse case ctrl+F5, the variables get reset and bind to null.

So, what should I do for having consistent,request-bind attributes for every single request.

note that I am forced to use

org.springframework.webflow.execution.RequestContext

thanks in advance.
