I want to make an application that do the following:
Users can connect to an http local website (local area network). I need to know who is connected (maybe getting his/her IP address) and after that, send a text string.
I don't want they identify on the website, only connect and get the text that I send.
Can you tell me if I need to use multiuser server and how to get the IP address of the client or other data that indetify him/her? and also how to send through his/her internet browser the text string.
Thank you very much
