My rest based application is going to receive the encrypted username and password from an upstream application.
My application will then interact with a downstream application,the downstream application will implement some logic(takes 1 hour approx., don't know why) at their end and they will hand us over the response which we need to send back to the upstream application.
Now, is it a good idea to store the username and password in the cache for an interval of 1 hour as we don't want to persist sensitive information into the database.
