Advanced Onion Router is designed to be a client for OR network and intended to be an improved alternative for Tor+Vidalia+Privoxy bundle for Windows users. It is able to "force" a program and its plugins to use the Tor proxy regardless of its configured proxy settings.
Onion Routing is a distributed overlay network designed to anonymize TCP-based applications like web browsing, secure shell, and instant messaging. Clients choose a path through the network and build a circuit, in which each node (or “onion router” or “OR”) in the path knows its predecessor and successor, but no other nodes in the circuit. Traffic flows down the circuit in fixed-size cells, which are unwrapped by a
symmetric key at each node (like the layers of an onion) and relayed downstream.

What's New in This Release:
· new page: "HTTP headers" with options related to changing HTTP headers and showing HTTP requests and replies with or without full headers (LOG_NOTICE for headers, LOG_INFO for full HTTP traffic, original and adjusted)
· setting a public proxy in a client and intercepting it will cause AdvOR to chain the OR exit with that proxy (to bypass Tor blacklists)
· if proxy chains are detected, all requests for all proxies are rewritten to apply all configured restrictions for each proxy in a chain
· if Opera Turbo traffic is detected in a proxy chain, Opera's unique identifier and the screen resolution that are sent to the Opera Turbo servers are replaced with identity-dependent random values
· added support for keep-alive HTTP connections
· added support for chunked HTTP transfers
· added support for multipart HTTP content types
· added support for identity-dependent fake HTTP headers with custom user-agent, regional settings, fake extensions, fake OS, etc.; can generate fake headers to mask a web ...
