The Headers filter allows us to override headers sent by the container
that may be in conflict with what we want. For example, Tomcat will set
Cache-Control: no-cache for any files behind the security-constraint
below. So if Hudson is on a public server, and you want to only allow
authorized users to access it, you may want to pay attention to this.
See: http://www.nabble.com/No-browser-caching-with-Hudson- -tf4601857.html

<!- The value listed here is for 24 hours. Increase or decrease as you see
fit. Value is in seconds. Make sure to keep the public option ->
<init-param>
<param-name>Cache-Control</param-name>
<param-value>max-age=86400, public</param-value>

<!- It turns out that Tomcat just doesn't want to let
go of its cache option. If you override Cache-Control,
it starts to send Pragma: no-cache as a backup.
