You can use any browser (Mac, PC or UNIX based) from any machine to view a
MachTen Web server. For server development, of course, you should have a
local Macintosh browser, such as NCSA Mosaic (for MacOS or X), Netscape,
etc. Mosaic for X has been ported to MachTen and can run on any Macintosh
with MachTen X Window Software. Running any browser on a MachTen Macintosh
will let you display in loopback mode any Web pages that you are developing.
At the same time, you could also be 'surfing' the Internet and checking out
potential Web links for the pages your are creating.
