[ale] A new web server

[Terry Bailey]

The last time I installed Fedora, which was Fedora 9, there were no 
questions about a firewall.  This time when I installed Centos 5.2, 
it was necessary to answer a few questions about the software 
firewall which I suspect is iptables.  I wonder if it is a 
firewall  problem?  But you would think that if it was firewall, then 
the page would still not come down on  a browser refresh.  I think 
you are right in thinking that it is an OS problem.  All the 
directories are 755.

I tested it with a web page with no graphics and this time, it loaded 
immediately.  The code in the access_log was 200
