[undertow-dev] Async PUT (fileresource) handler.

Hello, I have added a small special-purpose PUT handler to a project of mine. I am using however a blocking exchange to read the uploaded data and put it into a file. This seems to work, but I wonder if it would be worthwile to do this async (with channels). When I understand NIO FileChannels correctly they emulate the non-blocking behaviour with their own IO threads, so I guess it is not really better to use it this way (in terms of occupied threads). But I wonder if somebody did some experiments of has ready-made code for it? Just for the record, I am using new File(FileResourceManager.getBase(), canonicalize(exchange.getRelativePath()) to work around the missing write support in the FRM. Thats fine of the application is not too complex and needs no abstraction, but I can imagine it would be better to have that support (for things like WebDav handler). Gruss Bernd
