This is just a guess, but I suspect that Active4D is not giving a 1.1
response because it doesn't support other HTTP/1.1 features such as keep
alives.
In 1.1, I believe that keep alives are assumed unless specified otherwise,
so if you want to avoid problems then you probably want to appear the
header "Connection: Close", unless you are using 4D 2004 and its keep
alive support.
