    The high level abstraction you mentioned in last email give me a
nice guide... 

    I seached available apis. and I found luci.sys.getenv() is the
function to call. it returns a table with everything environment
variables.

    Below is the function I manage to print the environment variables
including REMOTE_ADDR



function action_tryme()
    local env = luci.sys.getenv();
    luci.http.prepare_content("text/plain")
    luci.http.write("<br> some text floows\n" .. type(env) .. "\n" );
    for i, v in pairs (env) do 
	luci.http.write( i );
	luci.http.write( "\t" );
	luci.http.write( v );
	luci.http.write( "\n" );
    end
end

-- the result is  -----

<br> some text floows
