How can I programmatically remove impersonation in ASP.Net?

Question

I have in my web.config, is there any way to programmatically "unimpersonate"? There is just one or two little places where I need to not be impersonating... is this possible?

Answer 1

The only way I'm aware of is to call the Win32 RevertToSelf function, do what you need to do outside impersonation, then reinstate your previous identity once you're done.
