UserControl with server in other port. CLR bug?

[Cedric]

I have a WebPage with a usercontrol (webcomponent.dll).
With the port 80 on the server, the webpage and the usercontrol works fine
If i change the port (18802), the time of loading the usercontrol is very long. After 30secondes it works fine
With the tool "Assembly Binding Log Viewer" (FUSLOGVW),
i see that the CLR search the assembly mscorlib.ressource on the server not at the port 18802 but at the port 80
This call are very long because there is no appli on the port 80
See the log at the bottom.
In the log we see ....net/18802/g55p instead of ...net:18802/g55p is it a CLR bug
Thank you to help me
