Fiddler Web Debugger is an excellent HTTP proxy debugging tool for Windows that includes a modem speed simulation feature (Main menu > Rules > Performance > simulate modem speed). 
Fiddler is freewarefreeware.

I also like Charles Web Debugging Proxy, a similar tool. Charles can also throttle the connection speed. Charles is commercial software, but has a free trial available. What I like most about Charles is that it is cross-platform: Being Java-based, it can run on Windows, Mac OS X, and Linux. (You didn't mention which platform you're on, but it's probably one of those :-)
