Web Application Proxy features

  • Preauthentication for HTTP Basic application publishing

    HTTP Basic is the authorization protocol used by many protocols, including ActiveSync, to connect rich clients, including smartphones, with your Exchange mailbox. Web Application Proxy traditionally interacts with AD FS using redirections which is not supported on ActiveSync clients. This new version of Web Application Proxy provides support to publish an app using HTTP basic by enabling the HTTP app to receive a non-claims relying party trust for the application to the Federation Service.

    For more information on HTTP basic publishing, see Publishing Applications using AD FS Preauthentication

  • Wildcard domain publishing of applications

    To support scenarios such as SharePoint 2013, the external URL for the application can now include a wildcard to enable you to publish multiple applications from within a specific domain, for example, https://*.sp-apps.contoso.com. This will simplify publishing of SharePoint apps.

  • HTTP to HTTPS redirection

    In order to make sure your users can access your app, even if they neglect to type HTTPS in the URL, Web Application Proxy now supports HTTP to HTTPS redirection.

  • HTTP Publishing

    It is now possible to publish HTTP applications using pass-through preauthentication

  • Publishing of Remote Desktop Gateway apps
