Wow. I've learned something today. Thanks! So without the Vary header, clients without gzip support might recieve gzip-encoded responses.

Yes. But if proxy does not support "Vary" header, it may send cached compressed to client that does not understand gzip.

And here we have two cases:

1) in Internet there are still many proxy servers that does not support Vary at all.

2) there are many browsers that does not understand compressing: if MSIE 5.5+ configured to work via HTTP/1.0 proxy it never sends "Accept-Encoding: gzip,deflate" and does not decompress gzipped responses.
