Pass Lua variable in proxy pass directive

[husaindalroti]

Hi Team,

Is it possible to pass lua variable in proxy pass directive which we define
using set_by_lua_file directive ?

Example :
set_by_lua_file $ref test.lua; 
proxy_pass '$ref';

Below is lua code :

local function main()
    local host="https://example.com"
    return host
end

return main()
