TFtpProxy is a module built for parsing messages of the TFTP protocol. It reads and parses REQUESTs on the client side, and sends them to the server if the local security policy permits. The answers are similarly parsed and returned to the client if the local security policy permits. Rewriting the requested filename and encoding is supported (although transcoding is not).

One proxy instance is able to handle more than one session, if the Router and Chainer classes support fast path operation (currently this is supported in DirectedRouter). This functionality is similar to, but different from the secondary session handling used in PlugProxy and RadiusProxy. In TftpProxy the parameters of secondary sessions cannot be set, they are managed automatically based on the logic of the protocol.
