Ehcache

Ehcache is a special kind of storage that is used to save things so that they can be accessed later on really quickly. Sort of like a toy box that you put your favorite toys in so that when you want to play with them again, you can find them really easily.

When a computer needs to read or write data, like instructions on how to play a video game or an email you want to send to your friend, it often takes a long time to do so because it has to go through a lot of steps. Ehcache helps speed up this process by keeping copies of the data in a special area of memory called "cache".

Think of it like a secret hiding spot in your room where you keep your favorite toys that you can always find quickly. The next time you want to play with these toys, you won't have to go through the hassle of looking for them because you already know where they are.

Overall, Ehcache is really useful because it helps make using a computer faster and more efficient. It works behind the scenes to keep the things you need close by, so you can get to them easily when you need them.
