With HTTP/1.0, there is only one safe option:

- don't compress anything for proxies.

With HTTP/1.1, there are two options:

- don't compress anything for proxies;

- compress for proxies, but send Vary to avoid incorrect behaviour.

The second options, which becomes available if you don't care 
about HTTP/1.0 compatibility at all, has its downsides I've 
talked about.
