How Internet Explorer downloads HTML-files through Download Manager

Summary

When a website wants to raise an Open/Save dialog for a resource, it can do so, by adding a "Content-Disposition: attachment" header to the response. If the document to be downloaded contains one of the following extensions, Internet Explorer will only provide Save, Save As and Cancel as choices in the dialog. Internet Explorer will hide the "Open" command in case Internet Explorer itself will be the default handler for the extension.

- htm
- html
- mht
- mhtml
- shtm
- xml
- xsl

After the download has been finished via the "Save" button, the information bar at the bottom on the webpage will then provide the possibility to open the downloaded document from the folder to which it had been downloaded.

More Information

This behavior is By Design and had been introduced with Internet Explorer 9.

The Content-Disposition is described in the following article:

In case that another application than Internet Explorer (e.g. Notepad.exe) will be default handler for the given extension, the Open-button will be offered and will then launch the application with the document.

A description about the configuration of the default handler is available at the following website:
