12.23 How come some objects do not get cached?

7. A 302 Moved Temporarily response is cachable ONLY if the response also
includes an Expires header.


And on checking out this banner we see:

$ lynx -head http://www.netregistry.com.au/ads/adview.php?bannerID=1

HTTP/1.1 302 Moved Temporarily
Server: Zeus/3.4
Date: Thu, 19 Jul 2001 21:37:36 GMT
Connection: close
Location: http://www.netregistry.com.au/AUNIC/hosting.gif
Content-Type: text/html
X-Powered-By: PHP/3.0.18


So No, this banner will not get cached in proxies.



For people who are particularly worries about banners, I suggest installing
Mozilla and running with Privacy options set to only load images that are
served from the same server as the current web page.

If you're *really* paranoid about banners and privacy, install Junkbuster.

p.s. personally I'm more worried that one of the registrars is running the
registry than I am about a piddly banner ad.
