More data.  Problem goes away when debug preference "enable disk cache" is
turned off.  I have seen complete web pages from other sites displayed at the
bottom of the www.mozilla.org.  Those web pages were not visited during that
mozilla session.  Hope this helps.

Build 2000052508 Linux.

I am unable to confirm or observe any behaviour similar to the report.

Reporter, can you provide detailed information about how you migrated your
Netscape profiles so we can reproduce more exactly?

After further inspection of my profiles for Netscape and Mozilla, I have
discovered the following:
Netscape profile is in /home/marcl/.netscape
Mozilla profile is in /home/marcl/.mozilla/marcl
Mozilla prefs.js has 
  user_pref("browser.cache.directory", "/home/marcl/.netscape/cache");   
/home/marcl/.mozilla/marcl/Cache is empty

It looks like Mozilla is trying to use Netscape's cache.  Perhaps there is some
incompatibility between the two caches (Netscape is 4.72).

Profile was migrated using mozilla -Installer

I am no longer able to replicate since the content of my cache is no longer
triggering the corruption (BuildID 2000052208).

Changing resolution to "works for me" as per reporters comments.
I couldn't and can't see the error either. (Currently M16 Linux 2000-052620)

My bug's been marked as a duplicate of this one. I don't think it's a dupe (mine 
is on Win 98, is intermittent, and I do not have the cache sharing) but if it 
is, this one should be reopened. Above are two attachments (GIF screenshots) of 
the bug manifesting itself in my browser.

Tom7 - added you to the CC field here.



Cache sharing isn't nessecarily "it" - it's just that there's been changes to

the way cahce works lately, and old files in the cache directories may have to

be deleted.

This MAY be a dup of other bugs, however:

There is bug 22701 - "garbage drawn in content area when page cannot be loaded".

If a page from that URL only partly loaded and was left in cache, from before

the latest cahche management checkins - well - then i *believe* this could be a

result. I'm guessing here, but please test deleting cached files and try load

the page again.

Again, my observation of this bug has been intermittent (the one reported here 
was persistent across sessions). Reloading displayed the correct page. I'll pay 
close attention next time to see if it happens on a page I've never been to 
before. The fact that I was able to view-source (as well as click a link and go 
'back' to the garbage page) make it clear that the garbage is being cached in 
memory at least, but I'm not sure if it was loaded off disk.

I believe bug 22701 has to do with graphical garbage rather than garbage 
characters appearing at the end of the html.

Please reopen this bug (I can't do it). I've observed it twice again with
2000052508/w98, and I do think it's a cache issue now:

First, I was fiddling with DNS/virtualhosts on my web server, and caused
www.domain.com to go to a different html doc. When I reloaded the page in
mozilla, the new (shorter) page was followed by the end of the old (longer)
page. A second reload fixed it.

Second, my first visit (I think) to a page was followed by the end of a page I
had visited recently with mozilla. Hash collisions?

reopening for more investigation.

I haven't had this problem at all.  I am using 2000060208 on Linux.  I'm going
to switch this to WORKSFORME.  We'll reopen it if needed.

[Tom 7]

This still happens for me all the time on Windows. Should I open a new bug?

Comment 14

[Asa Dotzler [:asa]]

Tom 7, are you still seeingthis in current builds?

Comment 15

[Tom 7]

Nope, haven't seen this in quite a while.
