I submit the form and it does not go anywhere... It basically refreshes the page. I am not sure if this is because I have error handling that says if a page does not exist then go back to where it was originated from.

Either way, the form submits but does not go to the controller I expect. It does work however when I dont try and use the subdomain in the front of the URL (<mySite>/dev instead of dev.<mySite>
