> im thinking you probly dont need a database unless you want to preserve chat history. i don't think chat history is necessary. but i need to keep some of the user chat session right? > but honestly, id really think about what youll be using the database for here.. well, i am still thinking :) .. if it is possible not to use database at all it is better. >hmm; well you need to make the client side smart.. like dont actually fire off an http request >as often if the last 3 queries all resulted in no new message. i did ask google. one way is to use a counter. if no new message, then increase the counter. On the other hand, reset the counter to zero. the counter multiple with the request time will make the request slower. anyone ever make use of /dev/shm on any php project?
