topic SecurityException, Cross Domain, Proxy Issue in ArcGIS API for Silverlight Questions https://community.esri.com/t5/arcgis-api-for-silverlight-questions/securityexception-cross-domain-proxy-issue/m-p/55407#M1427 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I'm fighting a weird issue but couldn't resolve it after a while.</SPAN><BR /><BR /><SPAN>I have a Silverlight project that uses local IIS web server. This project consumes 2 map services: base map from arcgisonline and a dynamic map service from local ArcGIS Server. Everything runs nice and neat. I later added a map screengrab functionality by creating a WriteableBitmap object. That causes a SecurityException in runtime. It's the cross domain issue, I knew it.</SPAN><BR /><BR /><SPAN>After adding ESRI-provided proxy page (with its config set to proper urls), updating both map services' ProxyURL, and putting a clientaccesspolicy.xml at local ArcGIS Server's root, that security exception still occurs. Finally, I turned to Fiddler but its log shows no response is coming back from arcgisonline, even though the map still renders when panning and zoning. I 'think' this is where the problem is but am not sure what else to do to fix it.</SPAN><BR /><SPAN> </SPAN><BR /><SPAN>Any advice is appreciated.</SPAN></BODY></HTML> Tue, 14 Feb 2012 13:05:08 GMT JasonLin 2012-02-14T13:05:08Z SecurityException, Cross Domain, Proxy Issue https://community.esri.com/t5/arcgis-api-for-silverlight-questions/securityexception-cross-domain-proxy-issue/m-p/55407#M1427 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I'm fighting a weird issue but couldn't resolve it after a while.</SPAN><BR /><BR /><SPAN>I have a Silverlight project that uses local IIS web server.
