Specify session file in url?

Replying here because this discussion seems more on-topic with the original question.

To avoid using the id here's what could work:

  • create an empty session with this in the root's onCreate script:
send('127.0.0.1:10000', '/session', globals.env.session)

this session will act like a hub and send the "session" parameter found in the url (like you did with the id)

  • set the server's load option to that hub session file
  • in the custom module, catch the outgoing /session message and use it to make the client load the session you want.

I have done this and it mostly works, thanks!

My custom module looks like this:

const default_session = 'default.json'
const sessions = {
    '1': 'one.json', // for client loading "http://server:port?session=1"
    '2': 'two.json', // for client loading "http://server:port?session=2"
    '3': 'three.json' // for client loading "http://server:port?session=3"
}

module.exports = {
    oscOutFilter:function(data){
        if (data.address === '/session') {
        	// don't actually send a message, load the desired session file
            receive('/SESSION/OPEN',
                (sessions[data.args[0].value] || default_session),
                {clientId: data.clientId}
            )
        }
        else {
        	return data
        }
    }
}

However this will NOT actually redirect from the "hub" session file to the target session file unless I add a small delay on create. This feels a little fishy too me as I suspect all I am doing is trying to fix some race condition with a delay. Eventually I'll hit some time when I lose the race and my session doesn't load. It also doesn't look very "professional" because my interface flashes when I reload due to the delay. Any ideas? For reference, this is what I ended up using for the onCreate script in the hub.json file:

  setTimeout(() => {
    send('127.0.0.1:10000', '/session', globals.env.session)
  }, 100)  // delay 100ms

cheers,
