Request parameters get lost after login.

When a request is made to a given secure sitemapitem with URL parameters such as /site/mynode?rp1=a&rp2=b
Then the org.hippoecm.hst.core.container.SecurityValve doesn't propagate the request parameters to the component that will process the request.

As a workaround, I've modified the source of the SecurityValve so that the request parameters are added to the httpSession and then retrieved by the component.
