only-if-cached

    What do this means? Who can I solve it?

        - Valid document was not found in the cache and only-if-cached
directive was specified.

         - You have issued a request with a only-if-cached cache control
directive. The document was not found in the cache, or it required
revalidation prohibited by only-if-cached directive.

    This happens when trying to use 'neighbor_type_domain' to treat a
sibling as a parent for certain domains.

    Thanks
