Help | A doubt with server.cpp

[hwpoison]

Hello! I hope you are fine.

I'm, trying to emulate a playground consuming the server.cpp api but I am having problems.
When I submit a prompt, in conjunction with the "as_loop" attribute to make it do a stream, I get the result token by token, but after try to stop the inference the next-token?stop=true with a GET petition and resend with POST new params and prompt, it continues to complete the previous one ignoring the new prompt.

I would like to know if you could solve this doubt, what exacly do the next-token?stop=true and how can i use it or about how to use it correctly, what detail I may be omitting.
