I found this [1] but unfortunately the post this refers to is

anything that I didn't already find in the docs.
What I can get from the form is the form fields with content,
the field name for the file upload and the file name. But the
file name is useless to me because I need the file content.
Where is it stored ?

hi, you can access HTTPServerRequest.files which contains the
uploaded file.
Example in real code:
https://github.com/WebFreak001/ImageUploader/blob/master/source/app.d#L141-L159
Documentation: https://vibed.org/api/vibe.inet.webform/FilePart
Note: the file is only downloaded from the client / stored on
disk once you access the files or the form property, though
this isn't documented.
Every post or example I found copies the file, like your code
does, too. Why is that ? The content of the file upload is
embedded in the form data. There's no need for temporary files or
copying at all.
On top of that, if I upload a file to a server which is on a
different PC on a different file system, how am I supposed to
read the file from disk on a remote file system ?
This makes no sense.
What I want is something like this:
~$ cat /var/log/temperatures.log
temp_1=22;temp_2=28
temp_1=21;temp_2=25
~$ curl -F "temperature_log=@/var/log/temperatures.log"
192.168.1.1:20222/temperature_upload
~$ nc -l 127.0.0.1 20222

string temp_data_raw = file.data;
assert ("temp_1=22;temp_2=28\ntemp_1=21;temp_2=25" ==
temp_data_raw);
}
}
