(Urgent) iRule for Http to Https on non-standard port

You can use a rewrite profile or a STREAM iRule, but ultimately you have to catch these bad URLs in server responses and rewrite them to match the external FQDN.

when HTTP_REQUEST {
    HTTP::header remove Accept-Encoding
    STREAM::disable
}
when HTTP_RESPONSE {
    if { ( [HTTP::header exists Location] ) and ( [HTTP::header Location] contains ":99" ) } {
        HTTP::header replace Location "https://someapp.corp.com/"
    }
    if { [HTTP::header Content-Type] contains "text" } {
        STREAM::expression {@http://someapp.corp.com:99@https://someapp.corp.com@}
        STREAM::enable
    }
}
