Notification page for selective URI's (F5 load balancer (version 11.2.1)

hello, are you using the F5 Access Policy Manager (APM) product for the logon pages and authentication? If you are then you can use the "Landing URI" option in the VPE to display a notification / message for some URI's.

Hi All - Thank you for your responses. Here is the iRule that worked for us.

when RULE_INIT { set static::debug 0 set static::cookie_expire_time 86400 set static::refresh_time 10 set static::notification_page " Site unavailable" } when HTTP_REQUEST { set mod_path [lindex [split [string trim [string tolower [HTTP::path]] "/"] "/"] 0]

if { $static::debug } { 
    log local0. "The variable mod_path is: $mod_path"
    log local0. "Refresh Time: $static::refresh_time"
}

switch $mod_path {
    "aaaaaaa" -
    "bbbbbbb" -
    "ccccccc" {
        if { $static::debug } {
            log local0. "Matched aaaaaaa pool!"
        }
        pool http_pool      
        }
    "ddddddd" {
        if { (not [HTTP::cookie exists NotificationDone]) } {
            if { $static::debug } {
                log local0. "Cookie was not set in ddddddd! Setting cookie!"
            }
            HTTP::respond 200 content [subst $static::notification_page] Mime-Type "text/html" Set-Cookie "NotificationDone=[clock seconds]; path=/; domain=.[HTTP::host]"
        } elseif { [eval [[clock seconds] - [HTTP::cookie value "NotificationDone"]]] > $static::cookie_expire_time } {
            if { $static::debug } {
                log local0. "CNotification Done Value: [HTTP::cookie value "NotificationDone"] Expire Time: $static::cookie_expire_time"
            }
            HTTP::cookie remove "NotificationDone"
            HTTP::respond 200 content [subst $static::notification_page] Mime-Type "text/html" Set-Cookie "NotificationDone=[clock seconds]; path=/; domain=.[HTTP::host]"
        }
        pool http_pool      
        }
    "" -
    "eeeeeeee" {
        if { (not [HTTP::cookie exists NotificationDone]) } {
            if { $static::debug } {
                log local0. "Cookie was not set in eeeeeee! Setting cookie!"
            }
            HTTP::respond 200 content [subst $static::notification_page] Mime-Type "text/html" Set-Cookie "NotificationDone=[clock seconds]; path=/; domain=.[HTTP::host]"
        } elseif { [eval [[clock seconds] - [HTTP::cookie value "NotificationDone"]]] > $static::cookie_expire_time } {
            if { $static::debug } {
                log local0. "CNotification Done Value: [HTTP::cookie value "NotificationDone"] Expire Time: $static::cookie_expire_time"
            }
            HTTP::cookie remove "NotificationDone"
            HTTP::respond 200 content [subst $static::notification_page] Mime-Type "text/html" Set-Cookie "NotificationDone=[clock seconds]; path=/; domain=.[HTTP::host]"
        }
        pool http_pool  
        }
}
