Configuring Application Offloading with SharePoint 2013

When the SharePoint 2013 server is accessed through an offloaded portal, basic functionalities, such as adding, editing, or deleting documents, tasks, or calendar events are supported. The client integration is supported if the offloaded portal’s authentication controls are enabled or disabled. However, when the Authentication Controls are enabled, the client is only supported on Internet Explorer under the following caveats:

• The offloaded portal created for SharePoint must use a valid certificate.
• The Scheme used by the offloaded portal and the back-end SharePoint must be the same. If the back-end SharePoint is running on HTTP, the offloaded portal must enable HTTP access and be accessed with HTTP.
• The same Scheme between the offloaded portal and the back-end SharePoint means that URL Rewriting for the offloaded portal does not need to be enabled.
• The Share session with other local application option must be enabled. This check box is located on the Portals > Portals > Offloading tab.
• The Restrict Request Headers option must be disabled. This check box is located on the Services > Settings page.
• If using Windows Vista or Windows 7 with the client, the offloaded portal should be added as a “Trusted Site” on the Internet Explorer browser. To configure your trusted sites, navigate to Tools > Internet Options. On the Security tab, click the Trusted Sites icon.
• The Share session with other local applications option must be enabled at login.
