There is APR_HOOK_LINK(request_status)
in mod_proxy.c. The request_status hook is an optional hook and I have the impression that this macro should only be used for non-optional hooks?
The macro publishes the apr_array_header_t for the hook, but optional hooks don't use those. They use apr_optional_hook_add() and apr_optional_hook_get() instead and do not need APR_HOOK_LINK.
Can this be confirmed? Regards, Rainer
