This commit is largely based on work by Thiago Arrais (@thiagoarrais)
and Shane Bradfield (@l33tLumberjack). I wasn't really able to get their
PR reasonably merged onto the latest master, so I reapplied their changes
manually here and did some further improvements on that.

# This scripts demonstrates how mitmproxy can switch to a second/different upstream proxy
# in upstream proxy mode.
#
# Usage: mitmdump -U http://default-upstream-proxy.local:8080/ -s change_upstream_proxy.py
#
# If you want to change the target server, you should modify flow.request.host and flow.request.port
def proxy_address(flow):
# Poor man's loadbalancing: route every second domain through the alternative proxy.
if hash(flow.request.host) % 2 == 1:
return ("localhost", 8082)
else:
return ("localhost", 8081)
def request(flow):
if flow.request.method == "CONNECT":
# If the decision is done by domain, one could also modify the server address here.
# We do it after CONNECT here to have the request data available as well.
return
address = proxy_address(flow)
