Christian,
J'ai essayé d'utiliser des connexions "socket" dans une page .irev
avec On-Rev, mais cela ne fonctionne pas. Paradoxalement, la commande
ne génère pas d'erreur. J'ai demandé à l'équipe On-Rev s'il existait
un exemple de chat, et voici la réponse:
"Thank you for your request. I have this response from our technical
department.
In terms of examples, not sure if there's anything out there at the
moment, but I could give a quick run through of how to write a simple
chat server in iRev.
Though server side CGI scripts are not ideally suited to the task it
would be possible.
If we were to consider a simple situation of a single chat room to
which users can connect, post, and read other's messages... We would
need a server side database that would store all the messages, when
they were posted and who posted them. We could then write a simple
iRev script that extracted all the messages from the database that
have been posted after a given date. In this case, our client app
would periodically call this script, passing the date as a parameter
and formatting the returned result for display. Essentially, the
client would be asking the server for all the messages that have been
posted since we last asked. The client would remember the date-time it
asked this question and then and use this the next time it asked. It
would simply ask the question by using get URL http://path_to_my_script.com
The server script would also take two further parameters that would
allow the client to post messages. This would be the user's name and
their message. If the server script detected these parameters, the
message would be written to the database and subsequently displayed in
any future requests. So, if the user typed a message into the client.
the client would simply include the message and the user's name as
parameters in its next periodic request."

Christian,
I tried to use “sockets” in a .irev page with On-Rev, but that does
not work. Paradoxically, the command does not generate an error. I
asked the team On-Rev if there was an example of chat, and and here
the answer: (see above)

Hello,
for my project I wanted to implement the simple chat server-client
stacks (or a similar solution using sockets), but I really have no
idea
how to start.
I'm new to sockets... and I want to use my on-rev hosting service...
Any help is appreciated :-)
