In Java servlet world: the servers do implement it partly.

That is, they understand Expect: 100-continue, and reply with 100 
Continue when asked for it.

However, the containers do not let the servlets have a say (inspecting 
the request, and potentially saying "417 Expectation Failed"). This is a 
restriction that has been known for a long time, and I certainly hope 
the Java Servlet EG will address that at some point of time (I haven't 
checked recently, so maybe they already did and I missed it).

BR, Julian
