htpasswd protect on port 9200 for all domain ?

hi,

i got elastcisearch on my webserver, and would like to acces via http on port 9200 for plugins, but only want to give access on port 9200 on all domains/ip for a restricted user, so user can't destroy my index.

i know how to restrict only on localhost, but n ow i can't use plugins webbrowser base script.

how to do this ?

restrict access with password for all port 9200 connections

Thanks,
bye
