Jetty Browser Cache Control

Do you use Jetty and need to change the default setting for browser cache control? Have a look at the init-param element named cacheControl in webdefault.xml.

Here’s the default configuration for the version of Jetty I use. Note the element is commented.

<!--
<init-param>
<param-name>cacheControl</param-name>
<param-value>max-age=3600,public</param-value>
</init-param>
-->

To enable and configure browser cache control, uncomment and edit the param-value as appropriate. The following example instructs the browser to disable all caching.

<init-param>
<param-name>cacheControl</param-name>
<param-value>no-store,no-cache,must-revalidate</param-value>
</init-param>

For information on Cache-Control, see RFC 2616, Section 14.9.
