  * @doc
  * OSBinet interface, and implementation of the VXIinet abstract
  * interface for Internet functionality including HTTP requests, local
  * file access, URL caching, memory buffer caching, and cookie
  * access. <p>
  *
  * The interface is a synchronous interface based on the ANSI/ISO C
  * standard file I/O interface, the only exception is that pre-fetches are
  * asynchronous. The client of the interface may use this in an
  * asynchronous manner by using non-blocking I/O operations, creating
  * threads, or by invoking this from a separate server process. <p>
  * 
  * This implementation currently does NOT support INET_MODE_WRITE for
  * http:// access (HTTP PUT), and only supports http://, file://, and
  * OS dependant paths.
  *
  * There is one Internet interface per thread/line.
