Is it a good practise to cache the object which is created using a factory?
For example i create a Customer DAO using the DAO factory then after creating it i store it in a hashmap in the factory and then when a different request comes instead of creating the CustomerDAO again i serve the same from the hashmap.

It is an attractive option as long as your cached object is designed thread safe or multithreading is not an issue in your application.
