EU eTranslation Proxy

This application serves as a simple caching proxy / gateway between the EU eTranslation Service and other applications requiring translation of text snippets into one of the official EU languages.

How it works

The EU eTranslation service is an ansynchronous service requiring an HTTP-callback or ftp / mail service to send the translated snippets to.

  • A third-party application sends a translation request via HTTP(S) to this translation proxy
  • If the translation is already in the cache/database, the proxy does not contact the eTranslation service
  • If the translation is not readily available, the proxy stores the snippet and sends a translation request to the EU eTranslation service
  • The EU eTranslation service sends the translation back to the proxy via the HTTP(S)-callback (or an error response)
  • Meanwhile the third-party application can send HTTP requests to the proxy on a regular basis ("is it available yet"), until the translation becomes available (or the client gives up)
  • The proxy will try again if the EU eTranslation service is not available or the maximum amount of requests is reached

Limitations

The snippet must be a plain-text snippet, with a maximum of 5000 characters.
