Adding secured services
You can add secured map services to ArcGIS Viewer for Silverlight via a proxy URL. Web requests are redirected through the proxy, which is responsible for authenticating with the service endpoint. Once you have configured your proxy pages as shown in the Configuring a proxy topic, you can access secured services.
Complete the following steps to add a secured map service to the application:
- Configure the proxy: Open the Application Builder and navigate to the Settings menu and click the Application Builder Settings tab. Enter the url to the proxy page in the Proxy text box. The proxy will be shared by all layers in the application that use a secured service. Close the Application Builder settings menu.
- In the Browse panel, check the Add Secured Services check box. All of the layers you add will now use the defined proxy.
- To change the proxy, click the Configure Secured Services button at the bottom of the Browse panel. When you change proxies for the application, the entire map may refresh if it has any map or image service layers that are secured. See the following screen shot:

- Add a layer using secured service only if it requires it. Currently, if Use Proxy is checked, all layers are added with ProxyUrl.
