  • Please note, this iRule is not tested but to get you started you can use something like below.

    when RULE_INIT {
    set static::notification_page { 
    <meta http-equiv="Refresh" content="10; url=" />
    <body><p><center>You are using old TLS settings. Please upgrade them to continue your access -<a href="">You are being redirected to original site</a>.</center></p>
        if { ( [SSL::cipher name] contains "RC4" ) }{
            set old_tls 1
        } else {
            set old_tls 0
    when HTTP_REQUEST {
        if { ($old_tls == 1) and (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]"
        } else {
