Can I put an object into varnish?

I want to push to Varnish specific url to cache it after processing. Flow:

  1. processing image
  2. when finished "push" url reference to the image to varnish to cache it

I do not want to wait for requests by clients to cache it then. It should be ready after processing to return it with high performance. Is it possible?

I can send an internal request GET like a standard client and make it cached, but I would prefer defining i.e PUT request in varnish config, and make it cached without returning it in that process.

Your only option is an internal HEAD (better than GET; it will be internally converted to a GET by Varnish when submitting the request to the backend side). The PUT approach is not possible, at least not without implementing a VMOD for it, and it probably won't be a simple one.
