RE: Integrated Windows Authentication and Session Timeout.



The NTLM credentials are sent on every request, but IIS and the LSA do some clever caching so they don't have to do a roundtrip to the registry/a DC every time.

server maintain the client state? is it through cookie?

How does the server maintain the authentication state? Is it through
cookie?
