Hi,

I think something like this should work: 

when HTTP_REQUEST {

    Save the requested host value
   set host [string tolower [HTTP::host]]


    Disable the stream filter by default
   STREAM::disable
}
when HTTP_RESPONSE {

    Check if response type is text and host isn't null
   if {[HTTP::header value Content-Type] contains "text" and $host ne ""}{

       Replace http://$host with https://$host
      STREAM::expression "@http://$host@https://$host@"

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

      if { [HTTP::is_redirect] } {
         HTTP::respond 302 Location [string map "http://$host https://$host" [HTTP::header Location]]
   }
}
