[Laszlo-user] "download" the XML from a dataset

[Henry Minsky]

I've never seen any web application do that, actually. There are definitely
security restrictions in Flash that prevent the
running app from directly accessing the disk. The browser almost surely
expects to download files via an HTTP
connection, and there is no way I know of to serve HTTP requests from within
a Flash application.

In DHTML, there is a mechanism called data URI
http://en.wikipedia.org/wiki/Data:_URI_scheme
which lets you encode a document as a string, and open it in the browser,
but I don't know which browsers
actually support it, and whether you could download a page which was created
that way.
