That's more or less what I had to do externally. I consider this a bug (or at least a really urgent feature request) that Cache doesn't do this on its own, since it could easily abuse a remote server.

Of course I never said that HTTP_Request has functionality to generate this $httpDate itself. It is left as an exercise for the reader.

You should be able to use the cache file's modification time (filemtime()) for this. -- Marshall Roch
