* $Log: BinHTTPURLInputStream.hpp,v $
* Revision 1.4 2004/01/29 11:51:20 cargilld
* Code cleanup changes to get rid of various compiler diagnostic messages.
*
* Revision 1.3 2003/12/17 00:18:37 cargilld
* Update to memory management so that the static memory manager (one used to call Initialize) is only for static data.
*
* Revision 1.2 2002/11/04 15:11:39 tng
* C++ Namespace Support.
*
* Revision 1.1.1.1 2002/02/01 22:22:23 peiyongz
* sane_include
*
* Revision 1.5 2001/10/25 16:26:39 tng
* [Bug 4213] BinHTTPURLInputStream initialisation not thread safe. By Mark Weaver.
*
* Revision 1.4 2001/01/22 16:43:39 tng
* Loads winsock dynamically. Fixed by Curt Arnold.
* Winsock2 is not initialized unless an http URL is used. If an http
* URL is used and the Winsock 2 DLL is not installed, then an NetAccessor
* initialization exception is thrown.
*
* Revision 1.3 2000/07/21 03:22:45 andyh
* Improved (but still weak) http access by the parser.
* Windows only. UNIX will follow, probably tomorrow.
*
* Revision 1.2 2000/03/22 00:21:10 rahulj
* Now we throw exceptions when errors occur.
* Simplified the code, based on the assumption that
* the calling function will make sure that the buffer into
* which the data has to be read is large enough.
*
* Revision 1.1 2000/03/17 02:37:54 rahulj
* First cut at adding HTTP capability via native sockets.
* Still need to add:
* error handling capability, ports other than 80,
* escaped URL's
* Will add options in project file only when I am done with these
* above changes.
