Description Sridhar Gurivireddy 2008-01-16 09:27:43 PST 
1) Navigate to finance.yahoo.com 
2) A network request goes out for http://l.yimg.com/us.js.yimg.com/lib/bc/bc_2.0.4.js
3) Close and open Safari again
4) Navigate again to finance.yahoo.com
5) Safari does not validate the cache for the resource.

However, IE does.

The title says "hitting back" - I do not see this in steps to reproduce. Could you please clarify which is correct?
Comment 2 Sridhar Gurivireddy 2008-01-17 11:21:28 PST 
It happens both when navigating back and launching a new instance of safari.

I don't know what's happening here and whether this is a bug, but this is probably decided upon by Apple frameworks beneath WebKit.

Why does IE revalidate? Is it a bug in IE? The response says:

    Cache-Control: max-age=315360000

That says it should not be revalidated until it's 10 years old!

Closing old report.
