Twisted Web includes an HTTP/1.0 protocol implementation for both servers and clients. It also includes a resource framework for implementing rich, dynamic web applications. It includes support for authentication either via HTTP AUTH, session URLs, or session cookies. It supports CGIs and a custom PB-based distribution mechanism for serving content from separate, persistent processes. It includes SOAP and XML-RPC support for both clients and servers. It also makes it particularly easy to deploy new servers with novel or ephemeral use-cases, often with only a single short command.
