Auto Login URL Odoo

URL to auto login is http://localhost:8069/web/login?db=mydb_10&login=admin&password=admin&redirect= 

But if you want to use above url we need to fix code in web module. Because you know when we pass params in URL we have to accept it using "GET" method in controller but currently Odoo use "POST" method.

I have fixed in web module and above url was working fine but issue comes when we try to log out that time it give internal server error.
So we can say if we use above url then log out feature will not work....
