Shoot- I left the abort in. Here's the non debug version!

Ok, I managed to isolate the problem. Here is what I found after some
digging:
The key problem appears to be when browser agents get passed through as
empty. When the condition happens, cfa_browser basically goes into an
untermintated loop trying to search for parents.
What I ended up doing was two things:
1) cfa_browser, when writing the agent string using browser update will
automatically trap out empty string agents and replace them with the
substitution 'unknown'.
2) cfa_browserCacheRefresh automatically purges any empty string browsers
from the browser.wddx file. This means that a simple restart should get you
up and running right away.
This is something that will have to go out in a hot fix of one form or
another, so it will likely show up elsewhere. I have attached the unit
tested files- <b>they have not passed our regressions yet, so please use
them with caution</b>. Let me know if you hit additional problems. . .

Charles,
As you know from my postings, and from the brower.wddx files that I
sent you, we can reproduce this with Netscape 4.5 for Win 95. If you
have a server that I can hit with this brower, I would be happy to do
so. Have you not been able to reproduce it with this Browser?
Thanks

So just to confirm, if you telnet to port 80, you get a corrupted
browser
file? The only file modified for 101 is cfa_browser, should be dated
3/23/00. The added lines are at line 163- here is the modification
made:
<!--- BEGIN: Modified by -pt, conceptware ag, 22.03.2000 --->
<cfset parentAgent = "Unknown">
<cfloop
condition="#Evaluate('#bNotFound#
AND (#nCount# LE #StructCount(stBrowser)#)')#">
<!--- END: Modified by -pt, conceptware ag, 22.03.2000
--->
Which basicallly terminates the loop if it has trouble locating a
parent.
I have been hunting for a reproducible case of the corruption on my
end, but
we can't get it to happen here. If you have a case or can give me
some
pointers, very much appreciated!

Hear, hear. We *are* using 1.01 (upgraded from 1.0) and experience
corruption with the browser.wddx file - just telnetting to port 80 is
enough
to break the system, presumably due to the unrecognised browser type.
Do you have any info about what cfa_ files we should check to make sure
they
are fully 1.01 and/or not corrupting any more?
Thanks,
-T.
