The htaccess file would be really helpful. Thanks in advance! Hi jack,

A. Etag : If you look at the last § of the etag rule : "If you're not taking advantage of the flexible validation model that ETags provide, it's better to just remove the ETag altogether. The Last-Modified header validates based on the component's timestamp. And removing the ETag reduces the size of the HTTP headers in both the response and subsequent requests."... Etag are just not really needed (at least for vinogusto)... B. Deflate & content-length I observe that while gzip-deflate is active, the server provides the content-length header : Headers (provided by Firebug) : Content-Encoding gzip Content-Length 6557 Keep-Alive timeout=15, max=100 Connection Keep-Alive Are you using apache on Linux ? I can send you my htaccess config... Hope this helps a bit. Regards, jack Hi Luis,

The Last-Modified header validates based on the component’s timestamp. And removing the ETag reduces the size of the HTTP headers in both the response and subsequent requests.”… Etag are just not really needed (at least for vinogusto)…

B. Deflate & content-length

I observe that while gzip-deflate is active, the server provides the content-length header :
Headers (provided by Firebug) :
Content-Encoding gzip
Content-Length 6557
Keep-Alive timeout=15, max=100
Connection Keep-Alive

Are you using apache on Linux ? I can send you my htaccess config…

Hope this helps a bit.

Having tried the deflate module... doesn't it remove the content-length headers of your requests? That's what I encountered, suddenly losing keep-alive support as it requires that header to be present. Regards, Hi,
