Rewrite rules can be conditionned with ACLs, so that's probably what you'd
like to do. You can even do that in your backend, for instance :
frontend xxx1
bind :1234
use_backend bck1
frontend xxx2
bind :80
use_backend bck1
backend bck1
# remove x-forwarded-for only for requests sent to port 80
reqidel ^X-forwarded-for if dst_port 80

I know some people who regularly do this, so I'm not sure what issue you
encountered with -sf. Are you sure you did not create a loop ?
