SharePoint User Group UK

I am trying to develop a session timeout warning for users on our Sharepoint platform. This platform has 2 load-balanced front-end web servers, and uses ISA Server, linked to Active Directory, and using NTLM authentication to authenticate users. When our users login, they use the ISA Server HTML forms to select the public option (10 mins) or private option (60 mins). Is it possible to develop some code which determines whether the user has signed in as public or private, and then gives them some kind of pop up warning (maybe Ajax?) that lets them know 2 mins. before timing out, that they need to 'click here' to continue their session.  Not sure how to enable the front-end web servers  to access this "session" information.  Cookie files are created on the ISA server when a user logs in (3 for private, 2 for public), but now sure how to communicate between the various systems.

Store the login info in session state and then add a user control in your sharepoint site using AdditionalPageHead delegate. This user control could contain the date and time logged in from the session variable and just use a bit of simple javascript to display the warning.

Just to clarify, to store the login info. in session state, I would use a Shared Services Provider, and then I could interrogate the relevant database?  

Also, I haven't created a user control before in sharepoint so any tips appreciated. Where would the javascript code be located?

Thanks

  

You would have to create a User Control within Visual Studio or an equivalent IDE. You could then create a feature to deploy the user control using AdditionalPageHead to get the control into all pages. The javascript would be on the user contol itself and you could spit the session variable out into the client side variable.

So, are you saying that the session information would come from session state and not from the ISA server at all - so there would be no way of distinguishing if they had logged in publicly or privately ?

Thanks.

Hi Julie,

As long as the variable is available to the server side code it will work. To be honest I have no experience with ISA server so cannot advise.

If you could get ISA server to pass the login expiry date through the querystring it might work. The user control could check the server variable and if the value is nothing it could obtain from the querystring and store it as a session variable.
