Hi all,

Our contestants feedback about the error as follow:

“Invalid CSRF token”, moreover contestants were frequently experienced with kicking out phenomenon and very hard to log back into the system.

Our configuration is briefly depicted as follow:

                

                                                     / domserver 1 \

Client ——> HW load balancer <                         >== Mysql DB

                                                     \ domserver 2 /

Please give me some advice to solve the issue.
