# Simplified Control Flow

Libwww is built on the request/response paradigm where an application issues a request for a URI (URL). Libwww then tries to fulfill the request as efficient as possible either by requesting the URL at the origin server, a proxy server, a gateway, directly from the local file system, or a locally cached version. Data is delivered back to the application as soon as it gets ready which guarantees minimum access delay for the application. Libwww is capable of accepting many simultaneous requests and handling them in an intelligent manner in order to save network bandwidth.
