Use Proxy Configuartion in custom node

How can I read the proxy configured in KNIME in my node to use it for requests?

Proxy handling is completely transparent, you don't need to care about proxy settings. If you open a stream on an http URL it will automatically use the configured proxy.

Could you explain in a little more detail what you meant. I can’t set up a proxy in my work in any way. For how many years. Can you please throw off the manual how to do it.
