Subject: [users@httpd] Apache / Websphere Open HTTP connection failed

Hi everybody

First, my apologies if this seems to be on the wrong list.  I've got a =
bit of a problem with an Apache/Websphere combination, and have no clue =
what I'm doing regarding Apache and Websphere.  I'm hoping that someone =
can offer a solution, or at least point me in the direction of one.

Short version:
Our site works just fine using Domino and Websphere application server.  =
It doesn't work with about 1% of our users when we run it with an Apache =
server instead of Domino.

The problem is Applets not loading, the exceptions we're getting are:
  "EOFException: Unexpected end of ZLIB input stream",
  "java.lang.ClassNotFoundException" and
  "java.io.IOException: open HTTP connection failed"

Server is running Win2K, Websphere 4.something (4.2, I think) and the =
Apache is the IBM HTTP Server that came with Websphere (again I don't =
know the version).

Any suggestions or guidance would be appreciated.
Thanks

Long version:
Our Web servers, a primary and backup, were set up by the contractors =
who did most of the Web development (Java servlets/applets).  Our =
management demanded that Domino would be the HTTP server, even if the =
project did not require anything of the HTTP server other than passing =
files back and forth.  The contractors went to a lot of effort to get =
that to work. =20

Recently our client/server folks had need to replace the one server =
(backup).  They got a new machine and installed Apache and Websphere on =
it, in the hope of demonstrating Apache's superior functioning and, of =
course, lower price.  Neither we nor they have any particular expertise =
in Apache.

Websphere was installed, ostensibly, in the same fashion as the primary =
(which has Domino).  They installed the same WAR (Websphere Archive) on =
the backup machine as is on the primary.  We swapped the backup (Apache) =
for the primary (Domino), letting the outside world get to it and it =
works fine for some 99% of our users.  But for some, less than a dozen, =
the applets won't load.  One sent a copy of thier console messages, the =
exceptions are listed above.

I will also point out that her console messages indicate that she's =
running behind a proxy, although I don't know if this is true for all =
the users who can't load the applets.  And, when she accesses our normal =
production site (Domino), everything's fine.

Also, her IT folks indicate she's using a NCD (Network Computing =
Device), which uses Windows Terminal Server to connect to the actual =
Win2K machine on which is running IE 6.0.

I might point out that the people who actually have access to the =
servers, and install the software, don't necessarily know anything about =
what they're installing.  Those who might have a clue about what's =
going, aren't allowed access, except under the most stringent =
conditions.=20

The process for troubleshooting this may entail going to another =
building, standing in a small room with lots of racks of servers, having =
a client/server guy log on, and watch my every key stroke while I try to =
figure out what's wrong.  I'd kinda like to have a clue as to which keys =
to stroke, where I might look for leads, and like that.  An error log is =
kept, I know, but I'm figuring that the errors are actually on the =
client side, and hence wouldn't show up server side. =20

One of the contractors who set it up in the first place, and is no =
longer on the project, suggested we check the MTU size, which we did and =
it's coded appropriately on both servers.  He's also suggested setting =
up a network monitor to observe what is actuallybeing passed.  I'm =
trying to arrange that now.
