JFile Version 2 provides three means of transferring data to or from the server: URLConnection, Sockets and WinInet (Note: WinInet is not available in JFile 1.x). The default transfer method for Windows/Unix/Linux with IE or Netscape 4.7x is URLConnection. The default transfer method for Mac + IE or Windows/Unix/Linux + Netscape 6.x is Sockets.

To transfer data through WinInet, set UseWinInet to 1.

WinInet is available with Windows and Internet Explorer only.   If the client operating system is not Windows, and/or the client browser is not IE, and UseWinInet is set to 1, JFile will use either,

• URLConnection
  If the client system is Windows with Netscape 4.7x or Unix/Linux with IE or Netscape 4.7x.
  
  OR
  
• Sockets
  If UseSockets is set to 1, or if the client is a Mac or Win/Unix/Linux + Netscape 6.x.  If both UseSockets and UseWinInet are set to 1, WinInet will be used on Windows/IE, and sockets on non-Windows/IE clients.

When transferring through WinInet, both the upload and download buffers are set to 16 KB. Decreasing the buffer size may impair performance, particularly with SSL.
