With a remoting service running in IIS I can access the session state, user,
application, etc using the RemotingService class.
What is the best way to pass a session from a console client to the server?
I assume this must be done with the HTTP header, but what is the best way to
do this?
Many thanks,
Christian

I think that the best solution is to use CallContext attributes. I use the
following technique:
1) I have class Session with all information that I need during session
processing
2) I also have class SessionID which consists of two GUIDs: session id and
hash, which is computed as MD5 hash of session id with some secret value.
SessionID is context-bound attribute which is returned from Login procedure
of my remote object.
3) Client must call Login method, obtain SessinID, put it into CallContext
and continue with other remote methods.
4) Every remote method implementation on server picks up SessionID from
CallContext, checks session id with hash and then extracts Session object
from Hashtable using Session id field as a key.
You can also create session expiration by setting DateTime.Now to some field
of session each time session accessed. Then you create a Timer-called
procedure which will remove sessions that was not accessed for 30 minutes,
for example.
Hope that helps,
Regards,
Gregory.

Hello Gregory,
thanks for the information, but I have used this technique you described for
remoting services that not necessarily run within IIS. This technique is
independent of the hosting environment.
Instead I want to make use of the ASP.NET functionality. The RemotingService
class already provides Session, Application, etc properties for the server.
How can I fill these?
Many thanks,
Christian

Christian,
I don't think you can use those classes. I think they're provided by
IIS/ASP.NET but not by "normal" remoting framework. But maybe I'm wrong...
Regards,
Gregory.

Now I've successfully used the User and Application property of the
RemoteService class in a .NET remoting server running in IIS, but the
Session is null.
How can I enable the session for the remoting server? Session is enabled in
the web.config file.
Many thanks,
Christian

Christian,
There is an attribute you can apply on method in webservice to enable it's
participation in session. Maybe you can try it on normal remote object?
Regards,
Gregory.
P.S. Can you let me know if it will work?

Hi Gregory,
No, it doesn't work. [WebMethod(EnableSession=true)] just works for classes
that are derived from WebService, it doesn't work for classes derived form
RemotingService.

Christian
