OneConnect Profile with Cookie Persistence

Dear,

Thanks for your response, i have left the oneconnect profile with its default configurations but you mentioned in your response that i should use source mask 0.0.0.0, how i change it, if i put 0 in the source prefix length it returns to none when i am updating the configurations: 

For the third point:, below are my configurations, should uncheck the expiration for the session cookie ? 

Thanks in advance,

Muhannad
