I am having the same issue with using bing map and having always use proxy condition true esri.config.defaults.io.alwaysUseProxy = true; Does anybody have a solution to this issue? I am kinda stuck here. I am using ArcGIS server 10.1 services with JS API Version 3.6. I have found a solution to this issue. I am posting it here for anybody having the issue. rule={proxyUrl:"/proxy/proxy.ashx", urlPrefix: <your map service url> } urlUtils.addProxyRule(rule); Visit this link for reference: https://developers.arcgis.com/en/javascript/jsapi/namespace_esri-amd.html#addProxyRule.
