I am writing a Flash (7AS2) chatroom for an MND awareness and community site, www.build-uk.net. The suggestion from the website administrator is that I build a chatroom using PHP and MySQL to store backlogs that the admin can flush occasionally.
Is this a realistic proposition? If I use Flash to automatically refresh a PHP script to generate new text content for a textbox, will this be too much of a strain on bandwidth? Will users on slower connections not be able to access the chatroom, the reload time being too quick?
