                     20: file called WWWApp.h depending on the needs of your
                     21: application. However, it is not required and none of the files
                     22: included below are ever used in the core part of the Library
                     23: itself. Only if this file is included, the extra modules will get
                     24: included in the linked object code. It is also possible to include
                     25: only a subset of the files below if the functionality you are after is
                     26: covered by them.

                     41: This module provides some "make life easier" functions in order to get
                     42: the application going. They help you generate the first anchor, also
                     43: called the <EM>home anchor</EM>. It also contains a nice set of
                     44: default WWW addresses.

                     51: 
                     52: You can register a set of callback functions to handle user prompting,
                     53: error messages, confimations etc. Here we give a set of functions that
                     54: can be used on almost anu thinkable platform. If you want to provide
                     55: your own platform dependent implementation then fine :-)

2.3       frystyk    62: 
                     63: When a request is terminated, the application often has to do some
                     64: action as a result of the request (and of the result of the
                     65: request). The Application part of the Library provides two following
                     66: modules to handle <EM>logging</EM> and <EM>history
                     67: management</EM>. You can register a <EM>POST request handler</EM> in
                     68: the <A HREF="HTNet.html">Net Manager</A> as described in the <A
2.4       frystyk    69: HREF="../User/Using/Overview.html">User's Guide</A>. <P>
                     70: 
                     71: You can find a function called <CODE>HTLoadTerminate</CODE> in the <A
2.5       frystyk    72: HREF="HTHome.html">HTHome module</A> that enables all the functionality
2.4       frystyk    73: for handling a request result.

2.1       frystyk    76: 
                     77: Often it is required to log the requests issued to the Library. This
                     78: can either be the case if the application is a server or it can also
                     79: be useful in a client application. This module provides a simple
                     80: logging mechanism which can be enabled if needed.

2.1       frystyk    87: 
                     88: Another type of logging is keeping track of which documents a user has
                     89: visited when browsing along on the Web. The Library history manager
                     90: provides a basic set of functionality to keep track of a linear
                     91: history list.
