Petr Abrahamczik 2.1 165 Před odhlášením z CAS je vhodné zrušit session v aplikaci klienta (zaleží to však na konkrétním klientu).
166
167 Pokud po odhlášení z CAS nechceme aby uživatel zůstal na odhlašovací stránce CASu, můžeme k odhlašovací url přidat parametr 'service', který
168 obsahuje url (nejlépe zakódovanou pomocí URL kódování) na kterou se má po odhlášení přesměrovat. Url musí obsahovat adresu, která je pro službu povolena.
