We have a similar issue with downloading a internal app for installation on the iPad. As the ipa is more than 11 MB, it takes time to download, but before it can finish, the iPad sends a cancel request to the proxy server. The timeout appears to be consistent at 10 seconds. If you have found the way to change the timeout, please let me know!
