The Drupal Commerce has a certain issue coming from at least September 6, 2012 on Multilingual or Non-English websites. The Order Total string can't be translated from Drupal's translation page. Thanks to jiaxin though a solution was provided to this issue 5 months ago. At last, all this comes down to a Drupal hook:
The drupal_http_request() function supports connections using a proxy. You can configure a global proxy to use for all drupal_http_request() callbacks from the settings.php file of your website/installation by filling the following lines with the proper information:For those of you preferring a UI, then HTTP proxy module is for you.But what if you only want to use a proxy in some cases; like a custom module? In that case you will need the following function(modify accordingly):Now all you have to do is Call <?php _MYMODULE_change_proxy(); ?>.Do your drupal_http_request() calls.Call <?php _MYMODULE_change_proxy(TRUE); ?> to reset your previous settings.
