simulating HTTP latency by chaining squids

[Nick Lewycky]

I was wondering if it is possible to tell my squid proxy to use another 
proxy for its own connections. I haven't been able to find any simple 
setting or anything in the documentation on how to achieve this. Perhaps 
there's some way to abuse cache peering into achieving this?

A real-world situation for this would be if I were given a proxy to use 
by my ISP and I want to run my own Squid on my small network. (The ISPs 
proxy is, let's say, a long satellite hop away.)

In reality, I'm trying to test the performance in my squid3 branch under 
different situations and I need a way to simulate additional network 
latency. This is the most promising solution I know of at the moment, 
but if anyone has a different solution (such as Linux netfilter tricks?) 
I can use, that would work just as well.

Thanks,
