title: Rails setting timeout in controller
body: <p>In my controller in Rails, I want to download a file into the <code>public</code> folder of the project (using the Linux system command <code>wget</code>). Then I'd like the file to stay there for an hour, before calling the command <code>rm</code> to delete it. Can I set a timeout so that the code execution pauses at some point before resuming later?</p>
