Stress Testing Generic Proxy

So I'm building some proxy software that any protocol can proxy over. I needed a proxy for a project I'm working on and I decided to make it generic so it's reusable.

In development I used a lot of telnet terminals. When it came time for stress testing I searched google images for the biggest image it could find. The first image was cool -- some kind of old black and white photo of a wagon in the snow. But it's website only worked if you pass the correct Host: parameter -- too much hassle. Would have been nice to look at...

So... I ended up using this 15 MB photo of the 911 towers:

I'm not sure if this should be depressing or interesting but I've been staring at it a lot during testing.
