To do so, you add a blank line in the HTTP 200 OK back, then access this CGI, and then paste it to download things, so that you can see the HTTP actual output is what.

The download time for the task is not to access your server, nature is not only in the beginning of the file name, when the task can be, generally will automatically change into your name
