180340 - Large cache defined but only recent files get cached.

Status: VERIFIED INVALID

(Core :: Networking: Cache, defect)

User-Agent:       Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-GB; rv:1.1) Gecko/20020826

I have set up a custom cache folder (j:\Mozilla), and my cache settings are set to:

Memory:20mb
Disk:30mb
Compare : "when the page is out of date"

I have also tried setting Disk: setting to much higher.

The problem is that when I look in the cache folder, there are only ever a few
files, never more than for the last 1-2 days.  This slows browser activity (I
have 56k modem connection).

Reproducible: Always

Steps to Reproduce:
1.Browse a lot over several days.
2.Check in cache file.

Actual Results:  
Notice that only few files are stored in cache folder, earliest date is previous
day.


Expected Results:  
Maintain longer cache history.

Will, can you type 'about:cache' in the URL bar after you've "browsed a lot",
and report the numbers back here.  That will give us a better idea of what's
happening with your cache.

Thanks.

I noticed it reset down to zero a few days ago, and it was immediately after a
browser crash  So it seems that certain types of browser crash zero the cache as
well.  My browser is 1.1.

If the browser crashes, we clear the cache on the next launch because the cache
is in an unknown state.

How often do you crash?  Every couple of days?  That would explain why you never
have files more than a couple days old.  If you think that could account for the
behavior you see, please mark this bug as INVALID.

There is also currently a maximum of 8192 entries in the disk cache, so it might
not be able to take advantage of large amounts of disk space.

Cache is being cleared by browser crashes.
