I don't see any problem here.

This is part of the request that results in a 304:

Host: qa40.fnismls.com
Connection: keep-alive
Cache-Control: max-age=0
If-Modified-Since: Fri, 21 Jan 2011 19:57:42 GMT
Accept: text/css,*/*;q=0.1
If-None-Match: "ae34d476a5b9cb1:0"

And this is part of the request that results in a 200:

Host: qa30.fnismls.com
Connection: keep-alive
Cache-Control: max-age=0
If-Modified-Since: Tue, 04 Jan 2011 20:43:39 GMT
Accept: text/css,*/*;q=0.1
If-None-Match: ""

So in both cases we have a cached resource and we are validating it with the server. However, the server doesn't like the second request.

Maybe I'm wrong, but as far as I can tell, ETag: "" is a perfectly valid ETag. Maybe using a constant (not empty) string does that you want?
