Embeded ActiveX in ASP Page

Hi
Im Working on a web site which embeds a user control class library .
This lib has strong name and should be added to the GAC.
my beginner questions..

1. I need to deploy this web site . how do I make sure the ActiveX is indeed added to client GAC and registered in his registry ?

2. The path of the activeX as stated in the ASP object id tag , is referenced to a location on the server . Does a copy of this activeX actualy being downloaded to the client's computer?
(I need to know that , cause Im thinking of adding sensitive data to this dll, data which I dont want the user to see in case he dissasable my dll)

Thank u very much
