I do not want to rule anything out, but a request I repeatedly hear is duplicating <form> functionality with XMLHttpRequest. Support for multipart/form-data furthermore is extremely widespread and resembles quite closely what is desired so it seems good to use it. If eventually we get native support for octet-arrays and all we can at that point add the ability to XMLHttpRequest so you can send anything you want. > If we do go the more specific route, then it could look like this: > > var data = new FormData; > data.appendText("name1", "value"); > data.appendFile("name2", fileData); > xhr.send(data); > > The UA could populate the filename attribute of the Content-Disposition > header based on the given fileRef.

This looks reasonable to me. I suppose we also want support passing File[Data] and FileList directly as I believe WebKit might have already added. Do you happen to know the implementation details? (I'm planning to wait with defining this until at least after TPAC. I expect more discussion to happen there and I also want to keep focus on the CSSOM before switching tasks again. It would be good to have most of the details before than though.) -- Anne van Kesteren http://annevankesteren.nl/
