exclude HTTP::header value Content-Type] equals "text/xml; charset=utf-8" from SSL redirect

AhmadJ I believe the following iRule should fix what you are referring to. I recommend testing this before putting into production or performing the change in off hours in order to minimize possible downtime if by chance the change is incorrect.

when HTTP_REQUEST priority 500 {

    STREAM::disable

}

when HTTP_RESPONSE priority 500 {

    if { ([HTTP::header Content-Type] contains "text/html") && !([HTTP::header Content-Type] == "text/xml; charset=utf-8") } {
        STREAM::expression {@http://@https://@}
        STREAM::enable
    } elseif { ([HTTP::header Content-Type] contains "png") || ([HTTP::header Content-Type] contains "jpeg") || ([HTTP::header Content-Type] contains "application/x-font-woff") || ([HTTP::header Content-Type] contains "pdf") || ([HTTP::header Content-Type] contains "svg") || ([HTTP::header Content-Type] contains "image/svg+xml")} {
        STREAM::disable
    }

}
