Query About Client Server Framework in symbian

Hi All,

I have the following query regarding the client server framework in Symbian:

Let Suppose Session is established between Client and Server. Now when Client sends any request to server, It will be called ServiceL of
the Session class. Lets have a following code snippet:
void Session::ServiceL(const RMessage2& aMessage)
{
Service the request;

}
Now Let suppose client sends an another request while server is executing the previous request, Does 2nd request will interrupt the ist
operation i.e. When One request is being executed, Will the ServiceL be called immediately as 2nd request comes or serviceL will wait
for the First Operation to finish?

If any body has idea , Please mail the reply.
