Oh Ok I found what the problem is, I guess my Varaibles in the onApplicationStart got cached, so when I sent it once, launched and then I added another Variables after launched again the application variables dont' get updated. Now How would i prevent it from getting cached? ------ Sherif Abdou http://VadexFX.com http://Sherifabdou.com ----- Original Message ----- From: "s. isaac dealey" <[EMAIL PROTECTED]> To: "cf-talk" <cf-talk@houseoffusion.com> Sent: Sunday, September 28, 2008 8:42 PM Subject: Re: onApplicationStart Vs onRequestStart
