From 59f1a41a7fdc03f5008e859e7e56e9c159b8a8d9 Mon Sep 17 00:00:00 2001 From: David Goulet Date: Mon, 1 Feb 2021 12:45:32 -0500 Subject: relay: Send back CONNECTION_REFUSED on reentry The TORPROTOCOL reason causes the client to close the circuit which is not what we want because other valid streams might be on it. Instead, CONNECTION_REFUSED will leave it open but will not allow more streams to be attached to it. The client then open a new circuit to the destination.
