Make a cheap web server with Revolution read write on port 80

[Jean Marc Delorme]

Hi from France!

The idea of this cheap html server came from "chat server" demo stack.
I tried, it works quite fine, and I use it for a true web service 
(carpooling).

Next is a simplified sum-up:

On Openstack
.  accept connections on port 80 with message GotAConnection

on GotAConnection aSocket
.  read from socket aSocket for 1 line
.  analyze received line (GET or POST)
.  read from socket aSocket with message GotNextLines

on GotNextLines aSocket , ReceivedLines
.  Analyze ReceivedLines
.  Do any processing you want with the user request
.  Make TheHtmlAnswer from pre-made file + replaced text (wanted GET file ou
POST answer)
.  if complete message received then write TheHtmlAnswer to socket else read 
again

Any distant web browser then gets the requested .html files (as forms with 
submit buttons), or POST anwsers after button clicks (submits) in previous 
sent forms.

Is'nt life easy?
The only limit is that only html text is replied (no image) because no 
Apache server is used.
Also have to record socket connections context in a gSocketConnectionsTable 
because many connections are available (which .htm file must be sent back 
when GotNextLines?).
Thank you for your feedback and own return on experience about making a web 
server from Revolution.
