Summary: Activity window does not show images which are cached
Product: WebKit
Version: 525+ (Nightly build)
Platform: Macintosh
OS/Version: Mac OS X 10.5
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: Page Loading
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: mysticalos at windstream.net
if an image is drawn from hard disk cache, activity window will completely
ignore image size/url on actual page. It will appear as if it does not even
exist.
This may seem like a minor bug at first. But i have already observed one such
website that is exploiting it by means of tricking Safari into loading blocked
content. i.e., you blocked banners.site.com in hosts file via 127.0.0.1 then,
go to that site. At first the images would be blocked properly. But when you
click any links on that site, it would redirect to a different path for the
advertisements. Then, it would cache those advertisements. Now when you return
to original page the blocked advertisements are now loaded from cache (and
hidden from activity window).
On Attached file. Download page to disk. open it in webkit. Observe that
activity window properly shows the background image. Then click the test page 2
url. You reload a near identical page with same image that loads straight from
cache and is totally obstructed from safari's view, activity window does not
show any existence of the image.
