Well, the proxy can't send a request on to the web app until it's been journaled, so the proxy will have to wait to receive the entire file anyway. Other requests can be forwarded to the web app while the file is still uploading... *IF* the web app is written correctly so that GET is always read-only, then you could even optimize things such that multiple GET requests could be forwarded concurrently, without journaling them.
