[Seaside] How to set the mime-type of a response?

[Julian Fitzell]

Hi Ian,

What you probably want to do is create the link to the document by 
calling #anchorWithDocument:mimeType:text: or #anchorWithDocument:text: 
on WAHtmlRenderer.  You could, for example, have a render method like:

renderContentOn: html
html
	anchorWithDocument: self myFileContents
	mimeType: 'application/pdf'
	text: 'Download my PDF'

It looks like whatever object you pass in as the document needs to 
implement asMIMEDocument, which at the moment seems to limit it to 
Strings, Forms, and Images.  I imagine it could be implemented for other 
things like Streams, but it would just have its contents pulled out at 
that point anyway.  The additional benefit of this method is that the 
document is cached so if it is downloaded again the browser will be able 
to use its cached version.  This is based on content so as soon as the 
document is changed it will have a different ID and will get downloaded 
again.
