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 {
<html>
<head>
<meta http-equiv="Refresh" content="10; url=https://www.site.com" />
</head>
<body><p><center>You are using old TLS settings. Please upgrade them to continue your access -<a href="https://www.site.com">You are being redirected to original site</a>.</center></p>
</body>
</html>
}
}
when CLIENTSSL_HANDSHAKE {
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]"
TCP::close
} else {
return
}
}
