[tor-commits] [flashproxy/master] Add local and remote proxy switching experiments.
commit 8a18185d9b2b353fd1442c1603518df2c3586f89
Author: David Fifield <david@xxxxxxxxxxxxxxx>
Date: Sun Oct 30 22:57:10 2011 -0700
Add local and remote proxy switching experiments.
These are mainly copied from the paper branch, but they use the nicer
new common.sh test infrastructure and are easier to run.
