Performing in-context review is easy using the Lingotek Translation module for Drupal.
Translations are automatically put back into your Drupal web site as soon as they have been created so there is no need for a proxy service. Once translated content has been pushed back to the Drupal web site, you can view it in-context before publishing the translation to all users. To make any last-minute changes as part of your review, you simply click on the Lingotek icon next to the content. This action will open the Lingotek Translation Management System (TMS) workbench where you can make edits, save, and then refresh the Drupal page to immediately see your changes.
