1. Squid The full
explanation about the term "Transparent Caching and
Transparent Proxying" depends on the context, but we can assume the
context here is HTTP proxy/caches with transparent hijacking of port
80, which is the default HTTP traffic in the internet.
Reverse proxy
cache, also known as Web Server Acceleration, is a method
of reducing the load on a busy web server by using a web cache between
the server and the internet.
Squid runtime
information like CPU usage, Memory usage, Cache Hit, Miss
etc.,can be monitored using SNMP (Simple Network Management Protocol).
Redirector is a
highly customizable program, which returns a new URL replacing the
client's original request. Squid sends the requested URLs to an
external redirector process, and the redirector in turn processes every
incoming URL, and returns either a new URL or a blank line to indicate
no change.
