What is a filter?

Last modified on July 27th, 2014 by Joe.

A filter is used to dynamically intercept request and response objects and change or use the data present in them. Filters should be configured in the web deployment descriptor. Filters can perform essential functions like authentication blocking, logging, content display style conversion, etc.
