==== Description: ====
The transproxy is a lightweight transparent non-caching proxy relay daemon,
written in python.

The daemon handles HTTP/HTTPS requests by converting them into proxy-aware
form and forwarding (relaying) to another/upstream proxy with optional "Basic"
authentication header inserted. Replies are sent back mostly unmodified.

Transparent redirection of e.g. all outgoing HTTP traffic is possible on
GNU/Linux platform with iptables:
iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080

Using iptables+transproxy has an effect of transparently "proxifying" all
application traffic, i.e. without need to reconfigure browsers, jabber
clients, without modifying http_proxy environment variables and so on.

This is most useful when you move between office/home zones and need to
switch between office and home proxies (or none proxy at all) accordingly.

There are alternative (caching) transparent proxy implementations like
squid/oops/delegate, but they are too much overhead for this purpose.

==== Other Software Required: ====
python, Python License,
linux/iptables, GPLv2,
