Get Post Data from drupal_http_request
Sorry. It's not answer. But i try debug in function 

function return_data_pcb() {
  watchdog("debug", '&lt;pre&gt;' . print_r( $_POST, true) . '&lt;/pre&gt;'); 
  // But $_POST is empty array. It's show in admin/reports/dblog, when in website one // call function drupal_http_request.
}


I don't know my problem by when call drupl_http_request data post doesn't not send. Or problem with hook_menu in website two. Please help!
