Web server which supports removing a file immediately after it has been downloaded once?

I need a web server that allows me to remove a file after it has been successfully downloaded once. Is there any way to do this with apache?

Is there another web server I can use for this task? I had already looked into Tornado for this purpose, but couldn't find a way to get an event to fire as soon as the download finished. the on_connection_close would only fire when I shut down the serv开发者_如何学Goer.

I'd prefer something PHP or Python-based if I have to code it myself.

you might be able to accomplish this with LUA (lighttpd + mod_magnet) - but im not sure... besides that im not aware of any modules that has event triggers on "downloads" there are some that work with uploads like the mod_uploadprogress in lighttpd. im sure nginx has some similar modules... besides that... i think the only solution here is:
