Does your HTTPService has useProxy set to true or false? If
true, and thus you're planning on using the ProxyService from FDS,
did you check the server startup logs to check that the FDS web
application started up correctly (that is, there were no
configuration errors)? If you are using the proxy service, have you
created a destination or modified the DefaultHTTP destination
accordingly to allow other dynamic-url patterns to be proxied
through the proxy service destination? If you're not using the
proxy, can you check that you can browse to the URL you're trying
to contact? Have you used the debug version of the player and
looked for more error information? Do you know about the security
sandbox and when to use a crossdomain.xml file?
