Explanation
- <filter-mapping> This tag specifies a filter name, and either a URL mapping or servlet name, for a filter that has been defined with the <filter> tag. Multiple <filter-mapping> tags can be specified for a single <filter>, providing different URL patterns. See the <url-pattern> tag for examples. The <filter-mapping> has two required elements: <filter-name> - the filter name, as specified in the <filter-name> element of the <filter> tag Either a <url-pattern> or a <servlet-name>. If a servlet name is specified, the filter will be called whenever the specific servlet is called.
