## Runing the examples
The examples can all be run from the Leiningen REPL.
Firstly, start the REPL with `lein repl`. Then the examples can be executed with:
* `(run simple-handler)` - A simple handler that just echos a constant string to the client
* `(run check-ip-handler)` - A handler that echos the clients IP Address back to them
* `(run echo-handler)` - A handler that echos the value of the "input" parameter back
* `(run request-count-handler)` - A handler with a session that tracks how many times this session has requested this handler
In all cases, the handlers can be accessed on http://localhost:3000.
