crossdomain.xml

Question

Hi,

I am having some problem accessing an exteranl rss feed in the georssfeed widgets. On my production machine, it works fine, however when i generate the release version and place on the server the georss widget complains about security error. I have a cross domain.xml in the root of the web server, however i am still having issues.

Any suggestions.

Can the need for a crossdomain file be circumvented by using a proxy server?  I am accessing a georss feed which works well in flash builder but when the project goes live on the server the feed does not appear.  I know this is because the server which hosts the georss does not have the crossdomain file - and are not about to place one on their machine.  So, could a proxy server be used instead of a crossdomain.xml??  Thanks!

I have a crossdomain.xml file in the wwwroot of my IIS server, plus one in the root folder of the my application - just for the hell of it. However, are you saying that my client needs a CrossDomain.xml also - to allow my app to access his services?

There is actually no need for a crossdomain on the machine where your application is (neither the root, nor the folder). The "cross" is from the application's point of view.   The crossdomain issues comes in to effect when that application tries to access the content on other server, like someone elses ArcGIS Server. In that case the crossdomain.xml needs to be on their server, e.g. http://machinewithgreatcontent/crossdomain.xml
 
The diagram on http://help.arcgis.com/en/webapi/flex/help/index.html#/Deploying_an_application/017p00000019000000/ might help clarify this.

The crossdomain.xml file needs to be on the server with the external RSS feed. Is that where you put it, or did you put it on the server that has your swf file?

I'm having an issue whereby I can't configure a Flex Template app to bring in feeds from a clients ArcGIS Server, as well as those hosted on my own ArcGIS Server. I have a crossdomain.xml file in the wwwroot of my IIS server, plus one in the root folder of the my application - just for the hell of it. However, are you saying that my client needs a CrossDomain.xml also - to allow my app to access his services?

thanks
