Identifying the caller

Hi!

This is probably impossible but I have to ask!

I have a WinService running a singleton serviceclass. Is it possible to
identify the caller of these methods and somehow put an id on them? For
example, most of the time, the service is called from an standard ASP-page
using interop. I would like to be able to see what calls that come from the
same asp page. I guess the entire script uses the same proxy class and that
the instance of that class would have a unique hashcode that might be
readable from the service?

What I would like to ackomplish with this is to be able to set a security
context for the user calling the service from the ASP script.

This is no high priority question at all, I'm just curios if this could work
somehow...


Thanks

Johan
