stateless http request in notification (REST not WS)

To push data to another system (here to our MES), we would like to execute by a notification an http request e.g. as composed by JSON (POST) or URI-Builder (GET), but not as a WebService (upgrade: websocket). Just using a simple stateless http-request. This opens up the possibility to push information to many other systems e.g. using apache with cgi-bin. The implementation effort on your side should be very small, because it's easier than a WS you already have. One thing I tried is to switch off by (re)setting the http header CONNECT and UPGRADE, but this is not possible / has no effect. This was alread asked in 2020 with some other topics but not really answered. Therefor this single idea.

    I revert to this, because it's working. I don't know what made it happen, but there is nothing to change. I wanted to show it to a specialist the tenth time and now it's working. My question remains, why it wasn't working before, so what's to do, that it's working at first try.
