I want to send a file to be downloaded via a "Save as..." type dialog in the client's browser. This requires a special set of HTTP headers. However, I would also like to update the requesting webpage at the same time, AJAX-style. Unfortunately, the two sets of headers must be different, and are not mutually compatible. My attempts so far have simply broken the file download, which is otherwise working.

Can I use a fork { ... } type of command to send back the file while still updating the webpage via AJAX? If so, how is this done? Which response should go back to the browser first, or does fork { ... } end up creating a race condition?

I'm not sure where to start looking for the direction to go with this, so any coding suggestions are welcome. Please note that I am not looking for a package--I have the downloading working already, and have learned to program the AJAX myself. I'm just needing to know how, if this is possible, to do both at the same time.

Blessings,
