I mentioned that already :
tcpdump shows that the content delivered by httpd has a content-type of
text/plain, the content delivered by tomcat has no content-type. So Andre,
your assumption is right.
httpfox would show the same.
I will check if i'm able to set the content-type in httpd, otherwise our
developers have to add a header in the http-response, setting the right content
type, or we will try a meta element in the head of the
html code, setting the content-type.
I will keep you informed.
