How to proxy an endless stream?

Question

ASP.NET

Hello, there is a task to proxy an audio stream. It was possible to send data to the outgoing stream, but firstly, they were not perceived by Media Player Classic as an audio stream, and secondly, I don’t know how to read and write it endlessly until the user closes the connection page (by closing the player).
Please help me solve the problem) Here's something already thrown
