I beleive your bug is probably related to Virtual Host... The target
site is probably having a Virtual Host define where the handler for
the JSP are't correctly configured... Removing the Host header just
make you use the default Document Root witch is badly configured and
does't Handle the JSP correctly...
To confirm this a easy trick would be to put the Host: header but
without a bogus hostname... You will probably have the same result as
if you would had not put the Host header...
I have alwready saw that behavior on a IBM_HTTP_SERVER I use as a
client, so I was not able to confirm if it was related to a virutal
host missconfiguration or not.
I would be surprise if your target is really a Tomcat server... If
they are using IBM HTTP Server (With is based on Apache), they are
probably running Websphere (Witch is IBM own Java Application Server).
