Hi Steve,
please try to implement the follwing method to avoid caching:
/**
* Interface method needed to be implemented in order to control caching
behaviour.
* When returning true, the served resource is cachable, otherwise it's
not cachable
* and the init method will always be called for each request.
* @return flag indicating whether or not the served resource is
cachable
*/
public boolean isCacheable ( )
{
return false;
}
Cheers,
Vedran
