2008-08-13 Tor Lillqvist <tml@novell.com> * win32/gwinhttpvfs.c * win32/gwinhttpvfs.h * win32/gwinhttpfile.c * win32/gwinhttpfileinputstream.c * win32/gwinhttpfileoutputstream.c: Refactor some common code snippets into helper functions. Check HTTP response status codes. Implement g_winhttp_file_query_info(), looking at Content-Length, Content-Type and Last-Modified. * win32/winhttp.h: Add some symbolic constants that are not publicly documented. Just a handful, so it should be OK to use information from the Windows SDK's headers. svn path=/trunk/; revision=7350
