you can replace "forward" with "external endpoint". coco forwards requests to HTTP endpoints. coco has a timeout setting that it applies globally. But we need to be able to set a higher timeout just for get-frame0-time. that's an "external endpoint" on carillon/fpga-master. In the coco config it's called a forward. The coco config defines "endpoints" as in endpoints coco offers. And it will forward the requests internally according to the config.
