Hi all!
I have a problem integrating Flex 3 - CF8.
Server platform: Debian/CF8/Apache2/MySql
On this server, I have 2 separate virtual host/website, say
"dns_service_one" and "dns_service_two".
In each of these, I have a CF application with a test CFC (see code below).
Session managament are enabled in applications.
In a test Flex application, I call each of two service exposed by the
server.
The problem is that the second call always fail, returning the error below.
Note that separate call will success. The remote service is up and working.
If I invert call order I obtain the same error.
I I move one service into another server with same configuration, the
application works well.
It seems that I can't call 2 separate service into 2 separate CF application
on the same server from a single Flex app ?
Code is below.
Sorry for the length of my question.
Thanks for help.
Roberto
