ajp_connection_tcp_get_message::jk_ajp_common.c (857): ERROR: can't receive
the response message from tomcat, network problems or tomcat is down
(, err=-1

The "tomcat is down" is IIS's response to Tomcat dropping the connection
after the exception.

It's strange that the 'bad' message and the 'good' retry message seem to be
identical (and perfectly valid AJP/1.3 packets).  Of course,  JK1.2.8-RC1
will send different packets now that Mladen has fixed header parsing, but
both forms are valid.  In particular, the Content-Length is the string "0".

I'd love to see the dump from the Tomcat side if you get a chance.
