I don't think there's any sitemap tags to that, if that's what you're asking.

You have access to the response object in:

* Generators
* Transformers
* Actions

So presumably you could write some code in one of these 3 places to do that.  Since an XSP
page is a generator, that might be a good place to do it.

But don't let actions scare you.  They really are very simple, and if that seems to be the
clearest way to something it's probably best to write one.

In fact the reason I wrote the "set_download" action was because:

1) I thought the sitemap (and my XSP pages) would read much clearer if I did, and
2) because I saw it had the potential to be re-used in either other places in this sitemap
or in other future Cocoon apps I write
