...According to the sample
"https://developers.arcgis.com/flex/sample-code/enriching-a-location.htm",
I need to use the app login to let client have access to the GeoEnrichment service without login to ArcGIS Online themselves. It seems I can use a proxy to do that like the sample did. "proxyURL="https://developers.arcgis.com/sproxy/"a
But I do not know how to config that proxy. Can anyone tell me how to do that?...
