2: Display the HTTP response headers for WML. 3: Display the content type response header for WML. Here you may notice something strange: the content type indicates the content is in WML, rather than xHTML or HTML. Google’s search engine seems to be defaulting to the oldest markup language, rather than the most popular one — why is that?
