whats caching code example

Example: what is caching

What is the caching mechanism?
Caching is just the practice of storing data in
temporarily and retrieving data from a
high-performance store (usually memory) 
either explicitly or implicitly. @CacheLookup
is used with @FindBy annotation and keeps 
that web element in memory and makes it ready
to use everytime. You can use that approach 
if you use any web elemnent frequently.
