Rewriting via Mobile devices is not supported/qualified.
For customers who have Bookmarks configured, please use the following workaround,
Users -> Resource Profiles -> Web -> Rewriting -> Selective Rewriting -> Created/Edit the Policy -> Select the action as “Don't rewrite content: Redirect to target web server” and save changes.
For access to intranet site, please use L3/L4 Tunnels as a workaround.
Note: PTP (Pass Through Proxy) is also not supported via Mobile devices.
