filter tag reference - novalexei/mod_servlet GitHub Wiki

#####<filter>

This is a container tag used to specify a filter and it's parameters.

A filter is run before servlets get called, so it's possible to "chain" 1 or more filters before the final servlet is hit.

There are two required elements:

• <filter-name> - the filter name, this is used to match the <filter-name> element in one or more <filter-mapping> tags
• <filter-factory> - the location of the filter factory method.

There is also one optional element:

• <init-param> - Define initial parameters for the servlet.
