WebDAV Specification thumbnail/preview file image

Question

Now I'm using WebDAV protocol for sharing files for writing my own webdav client.

I want to implement fetching thumbnails previews from specified file located web server (nginx/Apache/other). WebServer must generate thumbnail/preview image and return that with PROPFIND request or another way.

Is there any property from propfind or response header described in RFC and supported from webservers with nginx/Apache?

Answer 1

My answer is brief. There is no standard for this.
