#
#  to run PCTTY bank from within a NAT network
#
#  1) compile apache with mod_proxy
#  2) place directives like the following in your httpd.conf files


#  may not need this, but try it out
<Directory /home/cheffers/pctty/web>
AllowOverride FileInfo AuthConfig Limit
<Limit GET POST OPTIONS PROPFIND CONNECT>
Order Allow,Deny
Allow from all
</Limit>
</Directory>


# ProxyRequest On is usually dangerous for your apache server
# as anyone in the world can order any webpage in the world through you
# (and someone will sending your bandwidth bills way up there)
#
# However the following directories limit proxying to any URLS beginning from either
#
# http://192.168.1.    # this is your internal network
# http://calltty.co    # this should be the beginning of your URL
#
# Sadly, Apache only seems to allow 10 ProxyMatch configuration directives
# or you could completely protect your network.
#
# The idea is that you replace the letters in the regular expressions with
# the letters in your domain name.
# It is recommended you omit www from the domain name as this wastes 3 precious 
# characters out of the 10.

# Now construct a ProxyPass directive for each one of your PCTTY programs
#
# /pctty/web/pctty81.html is the web page name that the apache web server
# will accept (as if it were on its own machine) 
#
# and http://192.168.1.38:81/chatclient.html
#
# is the actual web URL for the chatclient.html webpage that PCTTY will 
# provide.  Apache web server will proxy to this URL when it receives a 
# request for /pctty/web/pctty81.html
#
# scheduler.cgi will have 'pctty81.html' in an array of PCTTY client machines
# that it will schedule

ProxyPass /pctty/web/pctty81.html  http://192.168.1.38:81/chatclient.html

ProxyPass /pctty/web/pctty82.html  http://192.168.1.38:82/chatclient.html


# this is an example of a windows machine with 2 PCTTYs running

ProxyPass /pctty/web/pctty81a.html  http://192.168.1.39:81/chatclient.html

# the PCTTY chat applet (at the customer's browser) will open a socket to
