SURVEY:AUTHOR1:SAME_VERSION_COMMENT[string] The client code for Thialfi is open-source and available at https://code.google.com/p/google-cache-invalidation-api/. Unfortunately, we are not able to make the server-side code available, since it is intimately tied with internal Google code and systems.
