how to handle external system session and login?

We have a monolithic java backend application which exposes APIs to front-end application so our java application is a server to the callers.



This application calls APIs from an external system which requires login first to get a cookie then uses this cookie while calling other APIs from this external system, so our java application is a client to this external system.



We need to find a way to handle the state between our java application and the external system for example when our java application gets several concurrent requests from the front-end to call the external system and the cookie was not valid, only one login request should be initiated to the external system to get the cookie and caches it then other requests should use this cookie.



is there a popular solution for handling such a case?

          How does a super-power salesman not get shut down for legal reasons?

          Image
          up vote 6 down vote favorite 2 I am in trouble: my boss, a multi-millionaire, has just come up with a scheme, but it has problems and he wants me to solve them. The whole thing started when he saw this picture: This gave him an idea: invent, develop, and sell "superpowers". These "powers" would not be biological (he's rich, but not that rich), but technological. Basically, he wants to have Small Hero Five-and-a-half (tm) working for him, constantly cranking out new tech. After he has his team invent the tech (with possible help from Anderson Robotics), he would start to mass-produce it (think: bat-mobile factory), and sell the gadgets (why sell the rights, when there is still more money to be made?) to would-be super-heroes. This is where the problems start: the reason no-one has done this yet, is ...
