Using the (FIXME: not yet implemented) frontend library, the extension triggers the Go client to listen on a local TCP port\n1. If a client application (VNC, SSH, etc.) connects to this local port, the Go client opens a HTTP upgrade request to the Rack server\n1. The Rack server parses the upgrade request and if everything is alright, responds back with a correct response\n1. The Go client establishes proxying between the local TCP port and the remote connection to the Rack server\n1. Based on the user-defined logic in the block passed to the Rack server, it opens a remote TCP connection\n1. The Rack server establishes proxying between the incoming request and the remote TCP connection\n1. The data flows freely in both directions\n\n## Contributing\n\nBug reports and pull requests are welcome on GitHub at https://github.com/skateman/purr.\n\n## License\n\nThe application is available as open source under the terms of the [MIT License](http://opensource.org/licenses/MIT).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fskateman%2Fpurr","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fskateman%2Fpurr","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fskateman%2Fpurr/lists"}
