You can set the outgoing data on the Request to post it to the server. Each call replaces the previous data. Encoding files for upload requires a little more work than simple forms. A complete MIME message needs to be constructed in the body of the request, so that the server can distinguish incoming form fields from uploaded files. If you need to add support for other URL types, you can register your own protocol handler to be invoked as needed.

The protocol open method takes a single argument, the Request instance, and it should return an object with a read method that can be used to read the data, an info method to return the response headers, and geturl to return the actual URL of the file being read. A simple way to achieve that is to create an instance of urllib. Since this is just a simulation, FauxNFSHandler is primed with the name of a temporary directory where it should look for all of its files.
