We have tried many many things, and seem to have narrowed it down to the session headers and the cache control. However all most all of the posts and notes around the web seem to get this issue arising with HTTPService calls that spawn a #2032 streaming error and not what we are seeing. Tracking the calls with Charles for instance seems to indicate that the call to the gateway is never actually being made. We discounted any crossdomain issues (the webroot and the gateway are on different servers) as the sandbox violation errors did not appear at all.
So if anyone out there can shed some light on this we would be most appreciative. Or conversely if you can get every person in the world to upgrade their browsers beyond IE6 that would be awesome too. mx.rpc.events::FaultEvent)#0 bubbles = false cancelable = true currentTarget = (null) eventPhase = 2 fault = (mx.rpc::Fault)#1 content = (Object)#2 errorID = 0 faultCode = "Client.Error.MessageSend" faultDetail = "Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'https://mydomain.com/amfphp/gateway.php'" faultString = "Send failed" message = "faultCode:Client.Error.MessageSend faultString:'Send failed' faultDetail:'Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'https://mydomain.com/amfphp/gateway.php''" name = "Error" rootCause = (mx.messaging.events::ChannelFaultEvent)#3 bubbles = false cancelable = false channel = (mx.messaging.channels::SecureAMFChannel)#4 PLEASE, help me... the whole application i'm working on depend on that.
