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.

I don't believe the temp file behavior is customizable as it is 
hardcoded here to write to a temporary file (which is called on 
form parsing): 
https://github.com/vibe-d/vibe.d/blob/ebebfa827f568cc9bced4bec2b66edc043a8adf7/inet/vibe/inet/webform.d#L311

However if you really wanted to (but I'd advise against it) you 
could parse the form data from the HTTPServerRequest.bodyReader 
yourself
