Right, ab known nothing about the contents of the replies, it
just validated that there is no major problems in mod_jk + TC 3.3.
The problem you expose recall me a very old problem in TC 3.3
which is fixed now, when using JSP and Redirect.
There may be still a problem in TC 3.3 and in that case we must
be able to reproduce it (may be in session handling). Could
you try using the native http connectors (port 8080) and
tell us if the problem still exists ?
