Don't use sockets. There is a better solution, namely gen_tcp (alias
ip_comm) which is a newer, more stable and faster tcp driver for the
emulator. Specify 'SocketType ip_comm' in your .conf files.

I think this is a bit confusing. inets.conf in this case is an
application startup file, while in the rest of the manual, the .conf
file references refeer to the Apache-style httpd config files.

Try this (assuming your 8888.conf is correct):
1> httpd:start("/var/tmp/server_root/conf/8888.conf").

This should fire up a httpd server on port 8888 (assuming you have
specified Port 8888 in the 8888.conf file).

Let me know if you have any luck.
