A simple, balanced proxy server which forwards requests to a backend / another proxy.
Start the proxy with command:
$ bundle exec bin/medusa start --ontop
Now connect to the internet via forwarded proxy:
$ curl --proxy1.0 localhost:9999 "http://example.com"
or use the provided script, which sends multiple requests in one go:
$ ruby clients.rb
and watch the colorized traffic flowing in your terminal.
You need the Bundler gem:
$ bundle install
The application contains an executable script which runs the server in the background, saves a PID file and logs output.
First, provide the application with an URL to a list of backend proxies, bind hostname and port:
$ cp config/config.example.rb config/config.rb $ vim config/config.example.rb
Then start the server (be sure to use the ‘bundle exec` command, to resolve dependencies):
$ bundle exec bin/medusa start -- production
Check that the server is running correctly:
$ ls -l log/medusa.pid $ tail log/medusa.output $ ps ax | grep medusa
You can monitor the service as you wish based on the PID file.
A “deathrow” check is performed in Backend.select. The URL of selected proxy is checked against medusa>backends>deathrow set in Redis. You are responsible for checking the status of proxies and adding/removing them into this set:
$ redis-cli > sadd medusa>backends>deathrow http://127.0.0.1:3000 > smembers medusa>backends>deathrow > srem medusa>backends>deathrow http://127.0.0.1:3000

Save “total” stats to Redis asynchronically

Create frontend web application with EventMachine and WebSockets to monitor the server
