How do you check whether a given type of error is logged in Jira just once ? An attacker can create thousands of tickets in Jira by just reloading a page that leads to a problem.

We do get several duplicates from users because they tend to click the same bad button over and over. I'm not too worried about attackers because you have to log in to get anywhere in our application. The way I have thought about doing it is having a sourceId in our ErrorReport class that would identify the report. The sourceId might be the page and breadcrumb trail or something of that nature. Then the ErrorReportingService would keep maybe keep a hash of the sourceId or store the sourceId's in the database and make sure others with that id are not sent for a certain time window. Although that is not perfect, because it could prevent errors from getting to us that need to. Can I make a new feature issue in JIRA for the DefaultExceptionMapper to pass the exception to the constructor of the internal error page? Maybe it could be a new type of UnexpectedExceptionDisplay in IExceptionSettings called SHOW_INTERNAL_ERROR_PAGE_WITH_EXCEPTION. That way it doesn't risk breaking existing users' internal error pages. With a patch would be awesome! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Pass-exception-to-internal-error-page-tp4664951p4664973.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
