A bit about WinInet's Index.dat

Since a recent digg article and its underlying Wikipedia entry seems a
little confused about index.dat, I�d like to give some more detail
about what it is and what we have changed with it in IE7/Vista�s
version of WinInet. As Jeffdav explained a while back, the index.dat
file is a store for web related things; the URL content cache, cookies,
RSS feeds, and visited links. Each of these collections, called a
container, has their own index.dat file that lives in the user profile.

First, let�s talk a bit about these containers a bit more:

On most machines the biggest and most important container is the URL
content cache index.dat. It lives (on vista) at
\Users\<user>\AppData\Local\Microsoft\Windows\Temporary Internet
Files\Content.IE5\index.dat. Content such as pages and images that we
fetch from the web and that are cacheable get placed into this cache
until they expire. The rules for if it is cacheable and when the
entries expire from the cache are complex enough to warrant its own
blog posting, but the common reasons that content doesn�t go in the
cache is due to the server telling us not to via response headers, or
the user telling us to not save any SSL resources to disk via the �Do
not save encrypted pages to disk� option in Internet
Options->Security->Advanced. Each cache entry has the URL and a file
name to allow us to quickly find previously retrieved URLs and serve
that content out of the content container. If a user just deletes all
the files in the directory, the index.dat file will still contain all
the URLs and paths until we realize that the cache entry is missing the
file, and should be deleted from the index.dat.

Mentions what's new in IE7 at the end of the article.  IE7 will zero
entries (overwite) when deleting.

I wonder how many of these changes made it to IE7 on XP?

16-bit PBD's V 32-bit PBD's
Does anybody know if there's any difference between 16-bit and 32-bit PBD files? Obviously the .exe files will be different between a 16-bit and 32-bit compile, but I'm curious about the PBD's. When I tested it they seemed to be interchangeable, but I seem to recall reading somewhere that it's not a good idea to mix 'n match them. I'm reluctant to clutter up my installation disks with two sets of PBD files if only one is needed! Charles Butcher Since PBDs are interpreted at run time, you can use the same PBD in a 16-bit or a 32-bit applications (external...

Hidden history lists
Forgive me if this has been discussed before. I opened user.dat (part of the registry) with wordpad and did find ASCII plaintext URL references to sites I had visited. As far as I know, this may contain a complete list of every site I've ever visited. I have tried all the zappers/washers/cleaners/ at my disposal. I tried wiping slack, deleting swap, nuking index.dat etc. Note that none of the above strings show up in a standard regedit search either. I've even tried rebuilding the entire registry by exporting all the keys and importing them in DOS. Nothing seems to...

Invalid index error
Hi all. When I go to any of our users who use GW6.5 and click on the checklist folder I get error C00E which states the following fix: C00E Invalid index number Source: GroupWise engine; database services. Explanation: Invalid index number. Possible Cause: When converting a post office from 5.x to 6.x, the post office database (wphost.db) was missing in the post office. Action: Restore the wphost.db file to the post office. Although the conversion does not actually use the old wphost.db file, it does attempt to access a file by that name in order to rename it. ...

Who's show is SN? Steve's or Leo's?
I don't want to start anything (honestly)! Just want to ask a simple question. Does the Security Now podcast belong to Steve Gibson or Leo Laporte? Maybe I'm in a world all to myself, but when I listen to the excellent SN podcasts, I want to hear STEVE, not Leo. But especially in the past few shows, it seems Leo will repeatedly interrupt Steve in the middle of a sentence that I want to hear the rest of. I consider this very rude of Leo. Steve is making a point that I (we) want to hear, then looses his train of thought after Leo barges in and asks something. It...
