I have tried my best to reproduce the alleged bug in my development environment
(which, I have to say, does not include Jakarta-Slide). Please see the test cases I
have used. It's been run with the following system properties to generate the
following dump

Everything appears to be kosher as far as I can judge. Tomcat 4.1.12 does send 100
status code when expected
Can you try running the same test case in your environment and let me analyse the
output it produces? Currently I tend to assume that the problem may be specific to
your development environment. Therefore, I would need a bit more help form your side
to narrow it down
Cheers

I am using as the server Tomcat 4.1.12 and a head version of Slide from few
months ago. The client is the current http-commons CVS head.
If I am running with -Dhttpclient.authentication.preemptive=true the
problem disappears.

Any ideas?

I think Tomcat works fine. If you send:
GET / HTTP/1.1
Host: localhost:8080
Expect: 100-continue
You get back (I tested 5.0.1-dev and 4.1.18):
HTTP/1.1 100 Continue
HTTP/1.1 302 Déplacé Temporairement
Location: http://localhost:8080/index.jsp
Content-Type: text/plain
Content-Length: 0
