[Zope-dev] Zope 2.0b1 on Win32 with IE5 - frequent hangs in management screens

[Brad Clements]

Can anyone else recreate this problem on their system?

Server/Client : Windows NT 4.0 SP4, IE 5. Server and client running on 
same machine.

Running Zope 2.0b1 binary as shipped just last week.

When viewing the management screens, if I don't perform any action for 
about a minute, then make a selection, IE5 hangs with the spinning 
globe for a long period of time, up to one minute.

Once the request has been answered, I can quickly manipulate the 
management screens so long as I make future requests within a "short 
period" of time as the previous request. In other words, if I just keep 
clicking away -- no problem.

Now for something interesting:

1. While IE 5 is "waiting for reply from server", if I make another request 
to Zope, either from the same machine or another machine, the pending 
request is immediately answered.

Specifically, where I might wait 60 seconds for Zope to reply, I can 
during that wait make another request from the same machine (different 
browser) or from another machine and the waiting request will get an 
immediate reply (and the second request also gets an immediate reply)

2. This "hang" never seems to happen using Netscape 4 as the client.


3. This "hang" doesn't seem to happen if the IE 5 client is running on a 
different machine than the server.

So .. this makes me think that:

1. In the win32 version of Zope
2. When IE5 is used as a local client
3. Zope is getting confused about some IE5 header in conjunction with 
the request coming from localhost
4. When another request is made, from anywhere, Zope "gets kicked in 
the ass" and stops blocking the first request..

Any ideas?

My NT system has a <winnt>\system32\drivers\etc\hosts

In that file is one entry, 127.0.0.1 localhost

Also I have a DNS server running on BSD 3 with PTR records for the 
host system..
