Here is the directory structure
webapp directory/downloadable_files/test.csv
webapp directory/downloadable_files/test.txt
The contents of these two files are the exact same. When I enter the URL for the .txt file (
http://website.com/reports/downloadable_reports/test.txt) it renders in the browser without error.
When I enter the URL for the .csv file I get two popup boxes. The first one that is running in the foreground is like a javascript popup box only the heading at the top of the popup is "Microsoft Internet Explorer" and the message is "Internet explorer cannot download test.csv from website.com.
Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later."
And there is a window in the background that is titled "File Download" but it is covered by the first window.
