I implement similar async file generation features in some apps. The approach I take is a little more involved, but keeps your interface async.

• Client sends a request for the file to be generated.
• Server sends response with the URL for the generated file.
• Client makes a second request to download the generated file.

This is invisible to the user, they will just need to wait for the second transaction to come back.
