Różne Viagry, Cialiasy, kasety video “One night in Paris” i sam nie wiem co jeszcze próbują mi dodać do bloga komentarze jak bardzo im się podobał wpis i jak jeszcze bardziej warto odwiedzić strony podane poniżej. Blog jest czysty, bo żaden z tych spambotów nie potrafi powiedzieć ile to jest 2+2 (swoją drogą boję się dnia, kiedy się nauczą). Problem w tym, że ostatnio w logu zaczął się pojawiać błąd CGI::Session::CookieStore::CookieOverflow. Ponieżej log:

Z tego co wyczytałem w dokumentacji, to standardowa sesja ma rozmiar 4K i przekroczenie tej liczby powoduje właśnie wyjątek: CookieOverflow. Problem się pojawia, gdy spamboty tworzą wielką wiadomość i return_to przyjmuje za dużą wartość.
Pytanie: Jak sobie z tym poradzić?
Z tego co rozumiem, to mam 2 rozwiązania:
- Nie korzystać w tej akcji z return_to i nie zapamiętywać tej ścieżki w sesji (słabe, bo wtedy tracę również zawartość komentarzy użytkowników, które nie przeszły walidacji).
- Wyłączyć loga dla tej akcji, ale to mi się nie podoba jeszcze bardziej, bo to takie zamiatanie śmieci pod dywan
No i dodatkowo jest problem, gdy użytkownik wpisze zbyt duży komentarz (więcej niż 4K) i nie poda np. adresu email. Wtedy jemu się pojawi taki błąd.
Jakieś sugestie? (Może ograniczyć liczbę znaków na inpucie?)
