Wt

If a file is to be shown in a plugin, you can stress this by adding a Content-Disposition: inline header. If you also add a filename, many browsers show the filename in the title, which is nicer than a random URL.

WResource should get a new method that allows the content-disposition to be set to inline or attachment.

Current situation:

suggestFilename -> Content-Disposition: attachment; filename=..

no suggestFilename -> No Content-Disposition header.

Desired situation:

suggestFilename -> Content-Disposition: [attachment|inline]; filename=...

no suggestFilename -> No Content-Disposition header.

Note: According to rfc2183.txt, you can only suggest a filename when you also set inline or attachment as content-disposition. However, you can specify inline or attachment without a filename. It has not been tested how browsers react on this.

The patch below demonstrates the principle.
