Question: Requirements for a custom server to support upload speed test

[julian-sotec]

For our use case we are trying to use a custom server for our speed test implementation.
Reason behind that is that devices need always need to connect to the same server and we want to ensure that the
internet connection speed is sufficient.
However since we could not find details on
how the servers in the standard list are setup we were wondering if there is specific requirements to a custom server.
Is it possible to use any Server URL as custom server that does respond with a 200 on a HTTP POST ?
I assume it isn't that easy... Any help would be apreciated.

There is no service side provided in this software. usually we use a standard speedtest server that supports the speedtest protocol(official version).
