so I simplified my irule and my issue is that I cant get it to drop the first directory form the URI. I have been trying many different things I found here but nothing seems to work.

First use hsl::open to define where to send logs and save it as a vaiable HSL

when CLIENT_ACCEPTED { set hsl [HSL::open -proto UDP -pool graylog2-syslog-pool] } when HTTP_REQUEST { HSL::send $hsl "This is the HTTP URI [HTTP::uri]" HSL::send $hsl "This is the HTTP Path [HTTP::path]"

set directory [lindex [split [string tolower [HTTP::uri]] "/"] 1]

set uri [string map {"/$directory/" "/"} [string tolower [HTTP::uri]]] HSL::send $hsl "This is the new uri $uri"

HTTP::redirect "http://$directory.domain.com/"

when this works I will append the new uri to the redirect

}
