Redirection behavior for upgraded web sites by SharePoint must be blocked.

Description
InfoPath automatically redirects user requests for sites that have not been upgraded to the temporary URL if it is located on the local intranet, but blocks them if the temporary URL is located elsewhere. InfoPath will prompt users before redirecting forms or form templates to another intranet site. If this restriction is relaxed, all requests to sites that have not been upgraded will be redirected to their targets, regardless of location. This functionality could cause requests made to a secure site to be redirected to an unsecured one (for example, requests to an intranet site could be redirected to an unencrypted Internet site), causing sensitive information to be at risk.
