Is there a way to reset the authentication used by IIS after a user has already been authenticated? I have a back end app that's pulling in the login variables and I'd like to be able to allow the user to login using a different account if needed. Here is the code i'm currently using:<BR> <BR> Response.Buffer = TRUE <BR> Response.Status = ("401 Unauthorized")<BR> Response.AddHeader "WWW.Authenticate", "Basic"<BR> Response.End<BR> <BR>It prompts the windows authentication box (three times), but doesn't appear to authenticate the user on the IIS server. Any help would be appreciated. Thanks in advance.
