I've been applying for quite a long time the famous jsp trick in order to prevent IE from raising a blocking popup. Everything has worked fine so far, until version 6.5.0. With releases 6.5.1 and 6.5.1.1, however, the Https.write method will apparently ignore the Media object's filename and content type. IE will ask me instead whether I wish to download the file "real-download.jsp" file. If I do so I get the actual file I had intended to get, it's only its filename and content type that gets wrong.
