Hello Maarten,

some code from Gjallar for doing this

 Rendering the anchor:

                            callback: [attachment downloadInSession: 
self session]
                            tooltip: 'Download file';
                            with: [ html html: attachment localFileName].

Attachment-downloadInSession: session

    | stream |
    stream := self readStream.
    session download: stream mimeType: stream mimeType filename: 

WASession-download: contents mimeType: mimeType filename: fileName
    self respond: [:url |
        (WAResponse new)
            contentType: mimeType;
            headerAt: 'Content-Disposition' put: 'attachment; 
filename="' , fileName , '"';
            headerAt: 'Content-length' put: contents size printString;
            contents: contents;

This download method is available as an extension to base seaside in
