I am now using curl HTTP to check the number of databases on the other side
 organizer A: 
 when I give him ac/pw, he will give me a session 
 I will record 
 he can also record 
 but now there is a problem 
 Container B: 
 when you log on to the same server again with server B, 
 the sesison of server A will fail, and the database of the counterparty will update this session 
, that is, the invalid session has expired 
 but how do I know that if the session of this server A fails 
 I will let him jump to the login window? 
 I"m already dead this time. 
 can you tell me a way? 
 because the current session of the database is permanent 
 I also use my own to buy my own
