filters life cycle:
The life cycle of a filter is managed by a container. Every
filter must implement the Filter interface. The life cycle
of a filter consists of implementing the following methods:

1. init(): This method is called only once after
instantiation to perform any initialization task.

2. doFilter(): This method is called after the init()
method. It takes three arguments, namely a ServletRequest, a
ServletResponse, and a FilterChain. It is called each time a
filter needs to perform any function. This method performs
the actual work of a filter, either modifying the request or
the response.

3. destroy(): This method is used to perform any cleanup
operation before the container removes a filter instance.
