Flex Security Error Accessing URL or Channel.Security.Error

August 11, 2008 16 comments

I had this wonderful error in a Flex Application that I couldn’t figure out.  Every time the app attempted to access the Web Service it returned the error “Security Error Accessing URL”. Well, thanks to this helpful site – – my problems have been solved.

Apparently there is a security issue with Flash 9.0.124 that requires the following line to be added to the CrossDomain.xml file:

<allow-http-request-headers-from domain=”*” headers=”SOAPAction”/>
