I just finished a credit card processing application for a
payment processor requiring the transaction data as an HTTP post.
To avoid Sandbox issues, I wrote a back end PHP program to relay
the post, parse the result and return it to the SWF on the client.
The Flex program is loaded using the Zend Framework Object Helper,
htmlFlash. Zend Framework provides the template for the site
(Layout) - the Flex program runs in one section of the template.
The program worked with no issues on my developmennt system.
When I pushed (both programs) to the same demo server I started
getting the "Security error accessing url" message when the
HTTPService is called. I am guessing the message is because the SWF
is invoked from the Zend Framework and does not recognize that it
is running in the same domain, but I am not certain. A
crossdomain.xml file on the server does not help.
How can I work around this? Would a proxy server in place of
the PHP program permit the HTTPService call? I am not sure which
approach to take at this point. Any help would be
