what is filter ?..

Answer / mukesh dhariyaparmar

A filter is a mini-servlet.Filters may record information about requests, convert to different format, or event redirect access to a different page. You can apply filters to any resources served by servlet engine, so it doesn't matter whether it's static HTML,graphics,a JSP page,or another servlet.One key advantages of filter is that it can be added to an existing Web application without either the filter or the application being aware of one another.
