I don't think I have, but just in case here is a copy of my gzip commands:
---------------------
# Serve up static compressed items
gzip_static on;

## Compression
gzip on;
gzip_http_version 1.1;
gzip_comp_level 2;
gzip_proxied any;
gzip_min_length 1100;
gzip_buffers 16 8k;
gzip_types text/plain text/html text/css application/x-javascript
text/xml application/xml application/xml+rss text/javascript;
# Some version of IE 6 don't handle compression well on some mime-types,
so just disable for them
gzip_disable "MSIE [1-6].(?!.*SV1)";
# Set a vary header so downstream proxies don't send cached gzipped
content to IE6
gzip_vary on;
---------------------

But with these commands things like jpgs and mp3s are still getting the
Vary: Accept-Encoding header, even though they are not compressed.
Is there something I am missing?

Thanks,
Zev
