I seem to having a new issue with this task. Thanks to Bernd I have managed to create named destinations within the PDF document. From there I have then created the email and linked the pdf url with the destination tag to open to that location. However what we're finding now is that once the PDF has been downloaded once, if you go back to the email and select another link it opens the PDF in the last viewed state.
This client has created one PDF containing many different articles. In the email she has created a table of contents and wants to link from each listed article to that destination in the PDF. But once you have clicked on one link, shut down browser, go back to the email and select another link it just opens what you were viewing last. Is this a cache issues? Are we using the named destination method in the correct manner?
We tried suggesting, linking once to the PDF and then from the PDF creating a table of contents with internal anchors however the client doesn't want this.
Suggestions?
