Nearly every modern webserver has optimized file transfers using
sendfile(2). You're not going to get any better performance by shifting the
burden of this task to your caching proxies.

Hi all,
I'm certain that it's possible, but am not sure how to do it: I want to
let my application create encrypted URLs, that are valid only for a
specific amount of time. I guess with the help of embedded C and
manually constructed hash keys this should be doable. Now I'm wondering
if may be someone already has done something like this, or as other
ideas to achieve this?
My idea is basically inspired by a lighttpd module:
http://trac.lighttpd.net/trac/wiki/Docs:ModSecDownload
The workflow would be something like
- decrpyt incoming URL
- rewrite URL, extract timestamp
- if not in range, send 404 (or what seems appropriate)
- if timestamp is ok, set hash key
- deliver object from cache or pull from backend
Thanks for any pointer,
Sascha
