RoxyProxy is essentially a lightweight ProxySelector that allows for
custom "proxy plugins": a pair of Proxy and Predicate with some
error-logging code tacked on. It's still in development, but certainly
useable.
The current code contains plugins for I2P (HTTP/HTTPS/IRC) and Tor Hidden Services, either with the default ports or on custom ports.
The easiest way to get started is to use RoxyProxy.install(...) for
the plugins you want. This handles the ProxySelector hooks and keeps
track of the specific reference for you. You could also manually
install the selector using
ProxySelector.setDefault(new PluginProxySelector(...)) for more
finite control.
I2PProxyPlugin.HTTP: proxies HTTP and FTP traffic for *.i2p domainsI2PProxyPlugin.HTTPS: proxies HTTPS traffic for *.i2p domainsI2PProxyPlugin.IRC: proxies IRC traffic for *.i2p domains NOTE: this will probably require a special library for full supportTorProxyPlugin: proxies all traffic for *.onion domains
Each of these classes has a .DEFAULT instance that represents the
default configuration out of the box for each of these. If you need
add another plugin, you can always extend ProxyPlugin and set up
your own rules. Feel free to submit a pull request if you make
something you think others would find useful.
