not possible to call CI controllers simultaneously?

Hi crafter,

thanks for your response. I don't use any js library.
Of course i could accomplish the same by polling, but it's not as efficient as only returning data when there's actually something to return

It does work when i call .php files directly instead of via de <url>/index.php/my_class approach. so it seemed logical to me CI has something to do with it.

I agree with you that it _should_ work, because each request is dealed with separately. The infinite loop is because i'll keep looking for changes while the page is active. On unload i stop the loop and everything ends.
