http - Chrome and IE cache static content, Firefox does not -
i trying improve performance of website adding cache headers static content.
so far, can content cache in chrome , internet explorer, not firefox.
here caching-related headers i'm supplying:
cache-control:private, max-age=1800
etag:"809067e0179acb1:0"
expires:mon, 20 dec 2010 21:35:10 gmt
(note: etag , expires variable; expires 30 minutes in future)
i verified behavior using fiddler 2. chrome , ie7 not request images, css, , js after first request, while firefox requests them every time.
is there header should supply make firefox cache these?
update 2010.12.22
i noticed same behavior on websites, including www.yahoo.com. there way force firefox cache?
this have occurred ssl content, should no longer case. firefox altered way caches resolution gecko bug 531801.
now, ssl content cached disk regardless of cache-control header.
