alert 4 all users

in my systems admins every few hours need to generte alert to all users...
i use ajaxed for this reason...user side checking every 30 sec some checkup and depends on the result alert being shown.
i wonder what kind of checking on the user side i need to check for this reason?

i should use sessions? or to open for every user column with what alerts was already shown to the user?

If I understand you correctly, you could write a page for admins to generate alerts that uses the ASP Application object. Then each page would check the value of the Application object when loaded. If the value contains an alert, then this could be displayed using a javascript popup etc.

is there a need for a application?

Not if each page is checking the database for new alerts. You would be able to use Session.
