Explanation:
Note:
* <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.
