We have a web based (ASP.NET) tool to author HTML content. Authors can create/edit HTML content, preview, and save the file as PDF. A 3rd party component- abcpdf is used to convert HTML into PDF. The converted PDF form will be distributed to consumers.
The PDF typically contains Hyperlinks, text boxes and submit button.
Clicking the hyper link in PDF should open the HTML in a new browser instance. It should not hijack (overwrite or reuse) existing browser instance that may be active in users computer irrespective of browser setting. Changing the browser setting IE: Internet Option > Advanced > Reuse windows for launching shortcuts is not acceptable by users.
