Hi,

Sorry for the bump, but this didn't fix the issue in my case.

I have static files that never change. I want to set future expires header for them and to force the browser NOT to check if the cached version is valid with if-modified-since conditional GET.

when I remove the Last-Modified header in nginx like Igor suggested, Only the expires and cache-control (max-age...) get sent, but I think the browser doesn't even save the resource in cache (tried with both IE8 and FF3.6).

This is my related configuration block:
[code]
location ~* \.(js|css|png|jpg|jpeg|gif|htc)$ {
expires max;
add_header Cache-Control public;
}
[/code]

Thanks!
