Yeah I think what he wants is a way to write the file into an
in-memory buffer. This is especially necessary it some
environments where you can write to disk at all.
How that's done, even in node.js is to use a middleware for
parsing library to parse the headers in such way. I often use
multer (which is also based on busybody) to do that in nodejs.
Unfortunately I haven't used D to that extent to need such a
thing... I in never hit that problem.
I wonder if using a psuedo file handler will work for the
in-memory buffer thing.
