> There is a session attribute called "_PREVIOUS_REQUEST_" used to remember and execute the previous request after a login occurs. This attribute is not removed properly when navigating away from a page without logging in.
> When navigating to a page that requires authentication the "_PREVIOUS_REQUEST_" attribute is saved in the session from within the LoginWorker to be called again when the login was successful through the RequestHandler. Currently, the attribute is only removed when a login occurs resulting in the previous request being stored in the session until some form of login is successfully executed.
> This behavior potentially results in navigation problems since a user is able to navigate to a page requiring authentication without logging in. An old request will be pulled from the session when a similar event occurs and the user logs in.
>  
> I propose to have the RequestHandler remove the session attribute "_PREVIOUS_REQUEST_" after calling a request that does not require authentication. We also have to restructure the sequence of request handling to have the "targetRequestUri" handled after the security check and a possible removal of the session attribute.
>  
> One problem arises with this solution, however, which should be less of an issue than the current state:
> If the login page includes a request call that is handled after the request showing the login page (for example an ajax call rendering a screen), the "_PREVIOUS_REQUEST_" attribute will be lost before the login is processed. To my knowledge such a case does not exist within the OFBiz environment and seems to be an edge case far less problematic than the above mentioned problem.
