16: This is the include file for all HTTP access including the

18: side</A>. It can be used together with the <A HREF="WWWCore.html">core of
2.12 frystyk 19: the W3C Sample Code Library</A>. It contains all HTTP specific modules which
2.11 frystyk 20: are required to compile and build the HTTP DLL.

59: The HTTP module also contains a very simple server module which can be used

114: and <CODE>Authorization</CODE> headers. Currently, the only scheme defined
115: is <I>Basic Authentication</I>, but <I>Digest Authentication </I>will soon
116: follow. All <I>Authentication Schemes</I> are registered at run-time in form

124: <P>
125: Contains code for parsing challenges and creating credentials for basic and
126: digest authentication schemes. See also the <A HREF="HTAAUtil.html">HTAAUtil
