10.1.7 cache
JSR 168 uses the <expiration-cache> for determining the cache. The interpretation of the cache value is the same for both portlet APIs. Copy the value of the portlet cache and then delete the cache elements. JSR 168 does not define shared cache so the expiration-cache element will just accept the cache value as shown in the following line.
<expiration-cache>0</expiration-cache>
