Currently, it is not possible. But such feature is a very simple for an implementations - we can bypass any parsing for a pages rendered without Richfaces components. I've created feature request in the project issue tracker : https://jira.jboss.org/jira/browse/RF-4095
Are you able to point me in the direction of where you think this could be done in the code? I'm more than happy to write a patch for it but we had little success trying this approach because the filter has no way of knowing which view you are going to, only the view you've come from (submitted to).
