im thinking you probly dont need a database unless you want to preserve

i don't think chat history is necessary. but i need to keep some of the
user chat session
right?


well it should be better performing; however, if a session goes down then
the conversation is pretty much toast; or at least half toast. id probly
stick it in memory or on a local filesystem.. hmm. im starting to see
where sqlite could come in handy.

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.


i dunno; id probly just use something like i linked on the last post. the
backend is php, so if nothing else you could look at the source.

anyone ever make use of /dev/shm on any php project?


i believe the sysv-ipc functions in php can give you access to that as well
(dont quote me tho; im to lazy to look it up atm :))
