Download dynamically generated content (e.g. KML) as file?

Question

Forgive me if this question has an obvious answer; so far I've come up with nothing.
Here's my scenario:  A user has data in a form in my Flex app and wishes to export the data to a particular file type (let's use KML as an example) and let the browser handle the resulting file in whatever manner it typically does so (open in Google Earth, for instance).  The current flow is:
User enters data;
User clicks "Export to KML" button;
Flex validates the data and converts it to valid KML;
Flex executes an HTTP POST to a JSP with the KML data as the content;
The JSP echoes the data in the POST as the response data, setting the content-type as KML.
This works fine, but I think I should be able to eliminate the JSP step.  However, I cannot find any way for Flex to directly handle setting up the HTTP response.
Any suggestions?
Thanks,
Doug
