We have a Flex/Flash application that loads information from XML files created by a .NET application. It works fine under IIS but when I try to run it from Visual Studio 2010 or 2012 using the ASP.NET Development Server, the Flex/Flash app isn’t loading the information. I brought up Fiddler and am able to see that there’s an error occurring when the Flash tries to access the XML:
[Fiddler] The socket connection to localhost failed.
ErrorCode: 10061.
No connection could be made because the target machine actively refused it 127.0.0.1:80
I’ve turned off my Firewall but that didn’t help. So, I’m not sure where the block is occurring. Any thoughts?
[Update: switched from Asp.NET Development Server to IIS Express and am still getting the exact same error.]
[Update2: I’ve verified that the XML file the Flash is trying to reach comes up fine in the browser: http://localhost:63318/ProductDetailsXML.aspx?ProductId=71%5D
It may have to do with it being served off of a specific port (not 80). How is your application requesting the XML file? According to your Fiddler log, it’s trying port 80, but your site is running on port 63318.
