commit f4fccee4d25b0de2780468b6f3b5b3b18d03945c Author: Nick Mathewson nickm@torproject.org Date: Tue Jun 12 15:21:41 2012 -0400

Add a warning for using HTTPProxy with no other proxy.

From what I can tell, this configuration is usually a mistake, and leads people to think that all their traffic is getting proxied when in fact practically none of it is. Resolves the issue behind "bug" 4663. --- changes/bug4663 | 5 +++++ src/or/config.c | 9 +++++++++ 2 files changed, 14 insertions(+), 0 deletions(-)
