This logic will fire only on the first access to a site during the session, then get out of the way for the remainder of the session. Something like this is what you're likely going to need to do:
when RULE_INIT {
set static::refresh_time 15
set static::notification_page {
System Notification
System Notification
This is an important announcement. You may need to take some sort of action, or no
action at all. It is important that you read this entirely. If some sort of action is
needed, then do it. Otherwise do nothing. That is all.
Wait $static::refresh_time seconds to continue, or click
}
}
when HTTP_REQUEST {
if { (not [HTTP::cookie exists NotificationDone]) } {
HTTP::respond 200 content [subst $static::notification_page] Mime-Type "text/html" Set-Cookie "NotificationDone=1; path=/; domain=.[HTTP::host]"
}
}

I know this is an older one now but I am using this to tell users that our page has moved and that they have until June 1 to update bookmarks. I am actually trying to use it on 4 different virtual servers but for some reason if I make a change to any one of the 4 irules (they each have a specific url to redirect to) then the F5 seems to cache the last irule and uses the same one for all 4 VS's.
Any clue as to why it would do that?

The static::notification_page variable is being set for all 4 irules. You can avoid this by making this variable unique for every iRule. For more info see:
