ok looks like the blog engine is removing the link to the JS file. It is just a regular js link but with the src set to AmIAuthenticated.aspx on the authentication server

Is what you output using Response.Write Missed out that bit on my original post... (after 'To do this output this to the bottom of your page using Response.Write or whatever:'

Kristin - Here is (half) a .Net solution that I use (obviously very easy to write in php, ruby - anything). Do not automatically redirect anyone who hasn't already got a session on your Single Sign-On Server. But how do I do this you ask! Ok, here we go... In your content page if an authenticated session for the user does not exist then you need to check the Single Sign-on server to see if there is one there, right? To do this output this to the bottom of your page using Response.Write or whatever: "" As you can see this links into a code page on your Single Sign-on Server, not a javascript file (you could set up isapi filters or whatever to make the extension map to the .apsx handler also). What does AmIAuthenticated.aspx return? This: ---begin code If (Session("username") Is Nothing) Then returnScript = "" Else If (Request.UrlReferrer Is Nothing) Then returnScript = "window.location = '" ConfigurationSettings.AppSettings ("SessionServerUrl").ToString() "';" Else returnScript = "window.location = '" ConfigurationSettings.AppSettings("SessionServerUrl").ToString() "?redirectUrl=" Server.UrlEncode(Request.UrlReferrer.AbsoluteUri) "';" End If End If ---end code So if there was a session it takes the user (using JavaScript window.location) to the Single Sign-On server to pick up there ticket! So you only redirect people if js / cookies are working, and if they have already logged into you Single Sign-On Server, not search engine crawlers! Ok, I think that should get you started... P.s. If you can't get this going it is because of my bad explanation, the method works, I am using it...

Not sure why a ticket benefits a crawler, actually I guess that's worthless, so why not checking for legit search engine crawlers and delivering those the contents without any redirects?

Right now, I am redirecting 3 times for every page visit. 1. Redirect to the Single Sign-On server to get a ticket. 2. Redirect back to the page (service url) from the Single Sign-On server 3. Self-redirect without the ticket parameter This ofcourse is pissing off Google's web crawler. Any solution to avoid this?

This is a great post for Googlebot dum-dums such as myself. I'm checking my server logs immediately.
