   In addition top the basic W3C Sample Code Library WWWLib interface you mayinclude the
   other interfaces depending on the needs of your application. However, it is not
   required and none of the files included below are ever used in the core part of the
   Library itself. Only if this file is included, the extra modules will get included in
   the linked object code. It is also possible to include only a subset of the files below
   if the functionality you are after is covered by them. This interface contains many
   application specific features including a set of default BEFORE and AFTER filters.

  System dependencies
  
   The sysdep.h file includes system-specific include files and flags for I/O to network
   and disk. The only reason for this file is that the Internet world is more complicated
   than Posix and ANSI.

/*

  Event Manager
  
   The core part of libwww only provides the hooks for the event manager. There is no
   event loop internal to the core part. Instead the application must provide the event
   loop in order to use either pseudo threads or real threads. If the application only
   uses blocking sockets without threads then it is not required to register any event
   loop at all. We provide a default implementation of an event loop which you can either
   take or get some ideas from.

/*

  Managing the Home Page
  
   This module provides some "make life easier" functions in order to get the application
   going. They help you generate the first anchor, also called the home anchor. It also
   contains a nice set of default WWW addresses.
   
 */
#include "HTHome.h"
/*

  User Dialogs and Messages
  
   You can register a set of callback functions to handle user prompting, error messages,
   confimations etc. Here we give a set of functions that can be used on almost anu
   thinkable platform. If you want to provide your own platform dependent implementation
   then fine :-)
   
 */
#include "HTDialog.h"
/*

  Load, Upload, and Search URLs
  
   Even though you may use the API for the HTRequest object directly in order to issue a
   request, you will probably find that in real life it is easier to use a higher level
   abstraction API. This API is provided by the HTAccess module where you will find all
   kind of functions for down loading a URL etc.
   
 */
#include "HTAccess.h"
/*

  Rule File Management
  
   Another way to initialize applications is to use a rule file, also known as a
   configuration file. This is for example the case with the W3C httpd and the W3C Line
   Mode Browser. This module provides basic support for configuration file management and
   the application can use this is desired. The module is not referred to by the Library.
   Reading a rule file is implemented as a stream converter so that a rule file can come
   from anywhere, even across the network!

#include "HTRules.h"
/*

  Proxies and Gateways
  
   Applications do not have to provide native support for all protocols, they can in many
   situations rely on the support of proxies and gateways to help doing the job. Proxy
   servers are often used to carry client requests through a firewall where they can
   provide services like corporate caching and other network optimizations. Both Proxy
   servers and gateways can serve as "protocol translators" which can convert a request in
   the main Web protocol, HTTP, to an equivalent request in another protocol, for example
   NNTP, FTP, or Gopher. In case a proxy server or a gateway is available to the
   application, it can therefore by use of HTTP forward all requests to for example a
   proxy server which then handle the communications with the remote server, for example
   using FTP about the document and return it to the application (proxy client) using
   HTTP.
   
 */
#include "HTProxy.h"
/*

  BEFORE and AFTER Filters
  
   _Before_ a request has been issued and _after_ it has terminated the application often
   has to do some action as a result of the request (and of the result of the request).
   The Client Profile Interface Library provides a set of standard BEFORE and AFTER
   filters to handle _caching_, _redirection_, _authentication_, _logging_ etc.
   
 */
#include "HTFilter.h"
/*

  Logging
  
   Often it is required to log the requests issued to the Library. This can either be the
   case if the application is a server or it can also be useful in a client application.
   This module provides a simple logging mechanism which can be enabled if needed.
   
 */
#include "HTLog.h"
/*

  History Management
  
   Another type of logging is keeping track of which documents a user has visited when
   browsing along on the Web. The Library history manager provides a basic set of
   functionality to keep track of a linear history list.
