Proxy error on Safari browser

[YamunadeviRathinasamy]

We are having Proxy.ashx/Proxy.config from ESRI. And the proxy works fine on IE. However showing error in Safari.
Access-Control-Allow-Origin

If you are seeing that error message, it means the proxy was not correctly configured (or the path could be wrong).

Yamunadevi,

are you talking about an error similar to the one seen in this sample?

XMLHttpRequest cannot load http://arcgis.storymaps.esri.com/ArcGIS/rest/info?f=json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://developers.arcgis.com' is therefore not allowed access. 

if so, thats a normal check made by the API to see whether the remote server supports CORS.
