That could very well be the problem. It might also be webperfcache:

I did try to compare the httpd.conf files, but the one on OS X Server

I noticed that the server where the problem occurs has the line
LoadModule proxy-module
The same line is commented
# LoadModule proxy-module
on my test machine where the problem does not occur.
Is this a bit of sneaky sabotage in Apache? If it was this easy to
destroy WebObjects' session model I think it would be well known

Hi
I've found a serious problem with my WebObjects application. It has
been running for over a year, but over the last few days users have
been reporting that the login name, which is displayed at the top of
the window, is actually someone else's, not the one they entered.
I didn't believe it but now I've visited the client and seen it for
myself. It's worse than they said. The users are actually all being
given the same session.
When several users log in within a short space of time the first one
gets a new session and then the others are given the same session.
The results for the application are catastrophic. It handles
vehicle reservations with most of the data for a booking being
carried in the session class. There are only a small number of
users as the application is only used within the company, but when
several of the reservations staff are actively editing the same
session things get very untidy very quickly.
I have done some simple tracing and found that
createSessionForRequest(...) is not being called when a new user
accesses the web server with the URL
http://myserver/cgi-bin/WebObjects/MyApp.woa. It is behaving as if
each new user was supplying a URL including an existing session ID.
I suppose this is what happens when cookies are used, but I have not
put in any code for cookies.
It does not happen when I compile and run the application in direct
connect mode and it does not seem to happen when I test deploy the
application through Apache on my development computer. - Mac OS X
10.3.6, WebObjects 5.2.3
It does happen when the application .woa file is copied over to the
remote server which is running OS X Server 10.3.6, WebObjects 5.2.3
I don't have exclusive control of the server. Is it possible that
the administrator has changed the configurations so it is holding
the session ID and giving it out to anyone who asks? When I have
tested the login procedure I have used multiple tabs in Safari to
login with different names, and then tried multiple windows in
Safari. I am assured it happens with multiple separate computers,
both Mac and Windows. Most of these computers would be on a LAN
sharing a DSL connection to the server which is remotely hosted. I
am told that even the small group of staff connecting from another
city may find they are sharing the same session.
Has anybody seen this? It seems to have only happened in the last
few days, but I can't imagine what has made it possible.
Thank you for reading such a long message.
