net2ftp - a web based FTP client. The normal way to connect to your FTP server is to use an FTP client and to communicate via the FTP protocol. This is however not always possible:
you may be behind a corporate firewall at work, which may block the FTP communications;
you may be on holiday and connecting to the internet via a CyberCafe, where you may not be allowed to install an FTP client.
When you use net2ftp these problems are solved: you connect to net2ftp using a regular web browser, and net2ftp translates your requests and takes care of the FTP communication.
