Session("timUserStartTime") = Now( ) Session("strUserIPAddress") = _ Request.ServerVariables("REMOTE_ADDR") ' Use the OnStart event to redirect the client if ' she attempts to enter the site from somewhere ' other than the site's home page. strCurrentPage = Request.ServerVariables("SCRIPT_NAME") strSiteStartPage = "/apps/home/startpage.asp" If StrComp(strCurrentPage, strSiteStartPage, 1) Then Response.Redirect(strSiteStartPage) End If ' You can also use the OnStart event of the Session ' object to assess user security access from the very ' beginning of the user's session. Note this code requires ' use of either the Basic authentication or Windows ' NT Challenge Response access control on the web server. strUserLogon = Request.ServerVariables("LOGON_USER") ...
