Similar to the post body of a form that has afile input element in it.Ultimately what I want to do is get a file off client machine (thatthey specify) and send it to the server using a standard post request.This is exactly the same as a form post with an file input element,but I don''t want to use a form, I want to get the file data andmanipulate it first then post it back.
