AJAX Call To Download A CSV File

I have a download summary page that loads after a users selects specific elements to include in the csv file. I would like to show the user the summary page and automatically start

Solution 1:

Try to do a window open in javascript than an ajax call. This will make the browser try to download the CSV than trying to read the CSV in javascript. The browser will stay on the same page (summary page) when the download starts.
