I'm trying to use a javascript locator object with a geocode server of ArcGIS Online: http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Locators/ESRI_Geocode_EU/GeocodeServer

When I call the method locator.addressToLocations(options), I get the cross-origin problem.

Is there a way to avoid this?

as mentioned in the header for this sample, when the server you are making calls to actually supports CORS, you can notify the JSAPI like this.


that being said, i don't think sampleserver1.arcgisonline.com supports CORS, so i'd recommend using our production World Geocoding Service instead.

in situations where you must work with a server that doesn't support CORS, or need to support browsers that don't support CORS, you'll have to configure a proxy and reference it in your application.
