I know about writing CGI application using Perl and Apache to refresh a static webpage that displays on the browser. But now i have an application requirement that I hope someone can help me.
The server side sits in another room down the factory plant, its monitoring some hardware environment, namely temperatures and pressures etc inside the plant. This server of course have Apache running. I would like to be able to have a browser in the comfortable office somewhere point to the apache server, and after I enter the password, it would display the temperature and pressures etc in the plant (in real time, ie. as the temperate changes from a degree to another, the browser will immediately display this). So I am looking more for a push technology than a pull from teh browser (user hit Ctrl-R to refresh is a pull). What are the current technology that allows for this. I know its possible because I can use my browser sometimes to chat with people online, and I swear that I don't have to do a Control-R everytime to see that the other person's typing is updating constantly on my browser. Thanks in advance, Push technology wannabe -- http://mail.python.org/mailman/listinfo/python-list
