Is it possible to have an ACL and http_access based on the User-Agent: Apple-iPhone/701.341 ? A test reverse OWA proxy we have is configured to prompt for authentication, and that would cause a problem with the Exchange email app on the iPhone. I want to have an http_access that checks to see if the request is coming from iPhone and allow access. I know the User Agent can be changed but this is a small start. - Nick
