Internal Program Version: tinyproxy 1.11.2 (The man files)

TinyProxy is a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems.
Designed from the ground up to be fast and yet small, it is an ideal solution
for use cases such as embedded deployments where a full featured HTTP proxy is
required, but the system resources for a larger proxy are unavailable.
