Course Stats Being Cached

[info2grow]

We are having an issue where different user accounts are getting different stats when downloading csv from the front end. The code on bp-course-ajax.php and statistics.php generates a file using the following logic $file_name = 'download_'.$course_id.'_'.$user_id.'.csv'; This title should be more unique to bypass server side caching.  Perhaps by including a timestamp.  Eg. $time_code = new Datetime("now"); $time_code = $time_code->format('U'); $file_name = 'download_'.$course_id.''.$user_id.''.$time_code.'.csv';

well we forcefully delete the file before generating new file with the same name . Please refer : http://prntscr.com/qxdsjn

I think the problem is that file was being cached by our server WPEngine.  Even if deleted it's still in the cache.  I get that we don't want to fill up the server but a unique name would definitely bypass this.  Perhaps a unique combined with a a wildcard reference to the old file to be deleted since it still has the unit/user ids?

restrict the url from being cached.
