Hi.

Currently I'm tried to make BlueBox work but without success.
The SmartFox server listens on port 9933 and Jetty is on port 443. A unity web player client, which is behind a proxy, is trying to connect to the server. We force the client to use BlueBox (by trying a first socket connection on a wrong port) but an error occurs :

Code: Select all

Http error creating http connection: System.Security.SecurityException: Unable to connect, as no valid crossdomain policy was found

Sfs2X.Core.EventDispatcher:DispatchEvent(BaseEvent)
Sfs2X.SmartFox:ProcessEvents()
ConnectionManager:FixedUpdate() (at Assets/Scripts/Server/ConnectionManager.cs:144)

Since the proxy allows HTTP traffic but doesn't allow a connection using Security.PrefetchSocketPolicy to get the crossdomain policy, how can we make a BlueBox connection with our server?
Do we need a TCP socket connection to get the crossdomain policy in order to make BlueBox work with Unity web player?

Another question : does the SmartFox .NET API use the browser/system proxy settings when trying a socket connection?

Thanks.

You will need to improve your crossdomain pre-fetch code to support the BlueBox.
I recommend taking a look at this thread:
viewtopic.php?f=20&t=14953

Another question : does the SmartFox .NET API use the browser/system proxy settings when trying a socket connection?

I have never tried in the browser, it all depends on the Web Player itself. If it is aware of those settings it will route the http calls accordingly

Hi. Thanks for the reply.

If you're talking about the Security.PrefetchSocketPolicy, I already do it on both ports; 9933 (normal) and 443 (BlueBox).
And I have this error log :

We'll need some time to investigate this further.
I'll keep you posted.

Thanks

UPDATE: I've looked further into this problem and there's definitely some issues in obtaining the cross domain policy.
The essence of the problem is that the crossdomain.xml file cannot be obtained via Security.PrefetchSocketPolicy(...) because it works with raw sockets but not HTTP.

So in the case where the WebPlayer comes from domain-1 and the connection to the BlueBox goes to domain-2 there is indeed a problem. I am surprised this hasn't been noticed before :shock:

but that's how it is.

I will follow up with another update as soon as possible.

Thanks
