sessions problem?

Hello,

 

I’m pretty new to Fluorine and I run into a problem that I can’t understand. I have a big background in Flex+PHP+Linux, but my current position I have to work with Flex+ASP.NET+Windows, so I have two new components to figure out.

 

I started out with the examples that come with Fluorine. I build forward on MultipleClientAuthentication. I’ve modified the SecureService class a bit (source below) and the flex part (doesn’t need any extra explanation). When I run the project on 2 different machines and I set the SecureData on one of them and on the other machine I do get SecureData the function returns the value that was set by machine1. What I expected that It would return me the default value.

 

So what appears to me is that Fluorine doesn’t create a separate session for every client that uses the app. But I need it to work like that.

 

I hope someone can help me a bit forward with my understanding of Fluorine.

 

Thanks in advance,

 

Mikhail

Thanks for this answer… I wasn’t experiencing this trouble, but the depth of your answer will help me in the future.

 

 

Hi Mikhail,

 

you defined a static ("global"/shared) _value member in your service. So any client connecting to the service will see the global value of this member (if client1 sets "some value" then everybody will get that value).

 

Static variables are not equivalent of "session variables", they are shared between all objects in the application domain.

Furthermore Session management is performed by the asp.net runtime and not the gateway. However from a service you have access to session variables via HttpContext(http://msdn2.microsoft.com/en-us/library/system.web.httpcontext.session.aspx) .... or the equivalent FluorineContext.Current.Session (so if you want to keep session data for the client then keep it in that dictionary and not in a class member).

 

Additionally services can have "session" scope (as defined in the Flex configuration files) which means that each client will get it's own service object so member variables (not declared static) will "act" as session variables. This case however is not recommended for any scenario.

There is a Flash sample illustrating this concept in the [FluorineFx Installdir]\Samples\Flash\Remoting\Activation folder (it does configure service scope by using Flex service config files)

Hello Zoli,

 

Thank you for your clarifying answer. The behavior of a static in ASP.NET isn’t really what I expected. At least now I know how to structure my code, so it behaves like I want. J
