With Apache::Roaming you can use your Apache web server as a Netscape Roaming Access server. This allows users to store Netscape Communicator 4.5+ preferences, bookmarks, address books, cookies, etc., on the server so that they can use (and update) the same settings from any Netscape Communicator 4.5+ browser that can access the server.

Available from CPAN. See the module manpage for more information.
