Based on the cache-info data provided (0x40020004), I'm inclined to
believe that the upstream server is closing the connection gracefully.
This is based on that data resolving to (from the help):
0x40000000 == Response should not be cached
0x00020000 == Response includes the CACHE-CONTROL: PRIVATE header
0x00000004 == Request includes one of these headers:
CACHE-CONTROL:NO-CACHE or PRAGMA:NO-CACHE.
..add them all up and you get 0x40020004.
Any server that is trying that hard to control where the data is stored
is also likely to make sure the connection is only open long enough to
transfer said data.
Unfortunately, only a packet capture can show this conclusively.

In addition to the directions I also cleared IE's cache. Then started
the
query and came up with the same results. Tried again with ISA caching
turned off (restarted ISA Services). Same results.

That's better...
>From that log, it appears that your clients aren't taking advantage of
HTTP 1.1 "keep-alive".
Try this:
In IE, go to "Tools", "Internet Options", "Advanced" and select "Use
HTTP
1.1" and "Use HTTP 1.1 through proxy".
Stop and restart all your IE sessions (yes, including the ISA MMC and
OL2K3).

Sorry about the partial... I'm probably going to overkill this, and I'm
sure you'll let know. :-) The times were identical.

That code resolves to '20000', a normal disconnect.
You really should refrain from sending "partial" log entries - the time
between connect and disconnect will help you determine whether or not
this
entry indicates a problem.

In IE websites like Dell's system configuration pages are blank, but the
previous page were displayed. The log query shows the following
sequential
line:
143.166.83.38 80 http Allowed All Open anonymous Internal External GET
http://
143.166.83.38 80 HTTP Closed Local Host External
Why is ISA 2004 closing the connection after allowing? The Result Code
was
0x80074e20 on the closed connection line. I looked at 284818 and this
number exceeds all values described. Is there a newer article or am I
heading in the wrong direction?
