I have to admit that I feel this is a stupid question, but two days of
Web search(1) and trials with WEBRick and CGI did not bring me any
closer.
Here is the problem:
I am uploading files to my Webrick server via the standard HTTP method:
<form method="POST" enctype="multipart/form-data">
<input type="file" name="data" /><input type="submit" /></form>
the Webrick do_POST handler than has the multipart/form-data in his req.body.
As astonishing as that sounds, I have not found a way to get the
file's content out of this.
I am sure there should be an easy way.
BTW I have browsed the ML archives and there are some references to
CGI but I just could not glue it together
All help is appreciated.

Here's something I found from Google. It may not be definitive, sorry,
but I think it can help!
Google didn't help me either, but I'm using a Ruby wiki called "Soks",
which runs on WEBrick and offers file uploads. Reading the code it
seems that the following should work:
upload_data = request.query["data"]
File.open(upload_data.filename, "wb") do |file|
upload_data.each_data do |data|
file << data.to_s
end
end
Take a look at WEBrick::HTTPUtils::FormData.
I haven't tested it, but I HTH.

That was indeed one of my first hits and it was useful to get the form
right, please note however that he is not doing anything with the
uploaded data :(, just sending it back.
And this exactly where it hurts, I cannot glue the received data
(req.body) into CGI, which would seem to do the multipart/form-data
conversion just fine.
Actually I would not care to save the body as such into a file and
have an external converter do the job(1), if I only had such an
external converer :(.
Thx anyway
Robert

I knew it would be simple, but that simple!!!
Works like charm.
Merci beaucoup Pit, meine Dankbarkeit wird Dir für immer nachschleifen

I thought I share the outcome of this, a very primitive file server we
need for some file transfer for folks caught behind a firewall and a
mean Proxy. Only https passes.
This might be useful for some low to medium traffic transfers.
I will use it on demand only, it is not really tested and there might
(there are for sure) some security issues. I have checked the most
obvious.
Runs on any system you can execute `df -k` in your Ruby code (that
part can be commented out if one needs to do so).
Hope this might be helpful in case somebody searches the archives for
