Crystal-lang file/image upload http server

Question

Is it possible to have a crystal based web server which handles file upload? I have been looking in the docs, and in many of the crystal web frameworks. I have not found any reference to a simple file upload feature anywhere.

Is this possible, or do I have to look elsewhere to handle my image-uploads?

UPDATED ANSWER: As of November 2016 you can use Kemal v0.16.1 and Crystal 0.19.4 for File uploads.

Here's how you can use it

post "/upload" do |env|
  parse_multipart(env) do |f|
    image1 = f.data if f.field == "image1"
    image2 = f.data if f.field == "image2"
    puts f.meta
    puts f.headers
    "Upload complete"
  end
end
