I was trying to have URLs like "http://example.com/myusername" and "http://example.com/myusername/about". Using Laravel, you're able to throw a wildcard in the prefix. The route needs to go at the end of the routes.php file if you have other static routes. #laravel

routes.php

<?php
// Routes for usernames
Route::group(['prefix' => '{username}', 'before' => 'valid-user'], function()
{
	Route::get('/', 'UserController@index');
	Route::get('about', 'UserController@about');
});

// Check to make sure the user is valid
Route::filter('valid-user', function($route, $request)
{
    // Get the username from the URL
	$username = $request->segment(1);
	
    // lookup username in user table, and if none exist, throw 404
    if (!$username)
    {
    	return Response::view('errors.404', [], 404);
	}
	
	// Will probably cache the username here, so it doesn't need a db query on every route
});
