Flush cache in Laravel 5.2 on shared hosting without SSH? - php

Question

2 questions actually:
How do I setup a Laravel site in a subfolder?
How do I flush/clear the cache?
My current situation:
I'm on shared hosting (don't mock me....I know dedicated server is better....trying to figure out how much budget to allocate for it so currently using shared since I can pay monthly) and can't use SSH.
URL structure is like this: website.com/v2 where "v2" is the subfolder where the site is installed on.
Is this the way my .htaccess and index.php are supposed to be setup?
.htaccess
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
RewriteBase /v2/
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
index.php
require __DIR__.'/../v2/bootstrap/autoload.php';
$app = require_once __DIR__.'/../v2/bootstrap/app.php';
For clearing the cache, I got this code in routes.php:
Route::get('/v2/configcache', function() {
$exitCode = Artisan::call('config:cache');
print_r($exitCode);
});
Are all of the codes above setup correctly? When I go to mywebsite.com/v2/configcache, I get an "Under Construction" message.
I need to clear the cache because I updated the database info.
