Has anyone used an ASP chatroom on their site? Are they reliable and if so up to how many users?<BR>I&#039;ve spent several months building one, which uses only Application arrays (and some querystrings) to pass info back and forth. It includes an instant messaging system and a mechanism to check if a user has closed his browser window.<BR><BR>So will this thing crash if I have like 20 people on it? Is a Java Applet really the way to go with chatrooms?<BR>I&#039;d be happy to share the code with anyone who would like to see it.
