       return function(conf,ctx)
       local mapping = {};
       mapping["new_domain"] =  "old_domain";
       if mapping[ngx.var.host] then 
        //what shall we do here...
         ngx.req.set_header('Host', mapping[ngx.var.host]);
       end
       end;
   phase: rewrite
   
   ```

   Update all existing router which related to `www.a.b.com`. Any hack is not recommended.
