Filters you can set for Apache Tomcat
Configuration information
Tomcat provides a number of Filters which may be configured for use with all web applications using $CATALINA_BASE/conf/web.xml or may be configured for individual web applications by configuring them in the application's WEB-INF/web.xml.
You also may delete docs and examples folders under the Apache Tomcat--> webapps directory. Web Viewer does not use these.
