No, the problem is just that you can't, as part of processing a single request, perform, for example, a mkdir followed by a cache lookup that might result in deferring and revisiting the request, because the wrong thing will happen when you revisit the request. With v2/v3, requests are simple enough that this shouldn't be a problem. But this is a bit harder to avoid when processing a v4 compound. --Bruce Fields ------------------------------------------------------- This SF.Net email is sponsored by OSTG.
