How to have 10% of requests rewrite

[kshaikh]

Guys,

I have a proxy which runs at http://xs.to.  It caches http://f0.ultraxs.com.  I need it to rewrite to a JPG 10% of the time.

I did this with upstream backend, but the issue was that the disk i/o really shot up doing that.

Is there a good clean way to run an if statement and rewrite 10% of the requests ?
