# Duane Wessels, Dec 1995
#
# Usage: tcp-banger.pl [host [port]] < url-list
#
# Sends a continuous stream of HTTP proxy requests to a cache. Stdin is a
# list of URLs to request. Run N of these at the same time to simulate a
# heavy client load.
#
# NOTE: does not simulate "real-world" events such as aborted requests
# (connections) and other network problems.
