I like that idea of finding/replacing the same string to avoid the replacement Nitass. Here's another option using a lookaround regex: 


when HTTP_REQUEST {
    Disable the stream filter for all requests
   STREAM::disable
}
when HTTP_RESPONSE {

    Check if response type is text
   if {[HTTP::header value Content-Type] contains "text"}{

       Replace any http:// instance with https://, unless the original string is http://www.no-change.com
      STREAM::expression {@http:(?!//www\.no-change\.com)@https://@}

       Enable the stream filter for this response only
      STREAM::enable
   }
}
