Proxy help?

Question

I am attempting to get the KML widget (created by Luke Berndt) working in my SFV 1.3. I think the problem I am having is that the KML file I am attempting to add is hosted on the web at a server location that uses an IP address. I currently get the following error when I try to point to this KML file in my config file:Error #2044: Unhandled SecurityErrorEvent:. text=Error #2048: Security sandbox violation: http://wcgisweb2.admin.washoecounty.us/Emergency_src/bin-debug/com/esri/solutions/flexviewer/widgets/KMLWidget.swf cannot load data from http://66.134.213.74/WildEarth/WildCAD_NVSFC.kml.

It is my limited understanding that Flex doesn't like SWFs that point to external data that is hosted outside of the local domain. I have read that in order to get around this, it is necessary to create a proxy file in ASP.Net, PHP, etc.

I have some questions about the proxy process...

1. Given my description above, is this the likely problem I am encountering?
2. Is there a brief and coherent description available of the proxy process and what it is actually doing?
3. Is there a brief and coherent set of instructions available for implementing the proxy solution (preferably in PHP)?
4. Is there another method of solving this issue without having to turn to ASP.Net, PHP, etc.?

In Firefox I just get a blank page. In IE8 I get an Internal Server Error.

I guess that probably means I don't have cURL setup correctly.

What happens when you load the this url directly in your browser?

http://server/proxy.php?http://66.134.213.74/WildEarth/WildCAD_NVSFC.kml

I setup cURL (I think). It shows up in my PHPinfo.php file as enabled.

I made the appropriate adjustments to the KMLWidget.ini and the proxy.php file, but I am getting this error:Error #2044: Unhandled IOErrorEvent:. text=Error #2032: Stream Error.

Maybe this just isn't going to work.
