Cool! Clearing cache between requests makes the second a HIT with
chrome!

First request after clearing browser's cache:
1292054351.774 37 127.0.0.1 TCP_MISS/200 617 GET http://www.elpais.com/css/i_portadillas.css? - DIRECT/80.156.250.8 text/css
...
Second request after clearing browser's cache:
1292054375.498 1 127.0.0.1 TCP_MEM_HIT/200 624 GET http://www.elpais.com/css/i_portadillas.css? - NONE/- text/css

Grats, you solved the issue! But I dont want to ask hundreds of sites to
apply the etag to their servers. Isn't there a way of using squid and
chrome and cache gifs, jpgs and css as firefox does? Maybe some obscure
squid ~"please-ignore-evil-etag"~ header? Or should we migrate to
firefox to use caching?

Thanks!
