Are you referring to the existing attempt at achieving "stop and write entire reponse to disk _while_ independently sending to the client"? All the large_disk_cache needs from cache to achieve this is access to request_rec, which it does in both #1 and #2. >From there it's a simple kevent or notifier equivalent to determine whether the socket buffer is free. Ideally, this should be abstracted into a convenience function in the core, somelike like ap_write_will_block(). Regards, Graham --
