Heh, I was waiting for someone to go there. Yes, you are correct that specific headers can be added to an HTTP request by the client which signal to the server that the request was made via an Ajax call. Strictly speaking though, they aren't guaranteed to exists. Regardless, the existence of such a header would in no way tell ColdFusion to ignore the usual session timeout-resetting that occurs with any other request to a ColdFusion page. ColdFusion treats Ajax requests like any other request your browser sends.

Where did you hear that? If the Ajax request is to a ColdFusion page that is part of your application it will most certainly keep the session alive. The server, after all, doesn't even know it is an Ajax call. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
