I think this is a newbie question. When Netscape doesn't realize, that a dtml-document is HTML (e.g. when I have a link to http://www.website.com/zope and /zope is a dtml-doc), what can I do? In the standard_html_header is the tag !doctype html public "-//w3c//dtd html 3.2//en" I thought this should be enough to let browsers recognize dtml as html. It is not relevant for the recognition as HTML.

DTML objects set the "Content-Type" to "text/html" by default. You need to do special things to prevent them to do this. Use Shane's "tcpwath" (or a similar tool) to see what HTTP response headers are sent for you document. Dieter
