demo/glacier2/callback problem

[alienwolf]

I tried the callback sample on one compiter today,and i was confused by the client's trace messenge .
here is the client trace messenge after the createsesion operation was invoked:
...

please notice the red text ,i just cannot understand when and where the getClientProxy and addProxy operations were invoked,i couldn't find the corresponding code in the client programme.

thx&Best Regards

These operations are from Ice::Router (see slice/Ice/Router.ice). The Ice core calls these functions to communicate with routers, such as Glacier.
