How do I force HTTP 1.0 response?

I’m trying to download firmware to ESP32 devices through cloudflare’s reverse proxy and the chunking is causing bad things to happen. They say that forcing HTTP 1.0 responses should help with this. Is it possible to do this with Lucee?

The solution/workaround - If you add a file extension to the resource so that it matches our list of supported file extensions so http://example.com/test/dynamicallyimage.php?size=3 becomes http://example.com/dynamicallyimage.jpg Cloudflare’s system will then send it with the content-length header as long as you’re also sending HTTP 1.0 as the protocol.
