I have seen a similar and possibly related issue with IE10. I don't use ColdFusion's ajax routines and instead use jquery but I have found that using ajax with a POST fails on some IE10 users whereas GET works all the time. Like your symptom, no alert or error of any kind displayed or logged. It does not fail for all IE10 users, only some which leads me to believe there is a security setting somewhere in IE to not allow ajax POST requests but I have not spent enough time to determine the issue -- I cannot duplicate the issue with my hands on IE10 testing.
