Software Requirements
We recommend that all recipient sites set up a proxy web server with caching capability, such as Netscape Proxy server.
If possible, all sites should use the same version of Netscape Navigator. This helps to minimize Tango interactions with browser-specific bugs.
Use a robust HTTP server to provide the course materials. Our experience suggests that some servers (Netscape Fast Track and Microsoft Peer Web Server) will hang during a typical class. The free HTTP server from Apache has been robust.
