README
A PSR7 middleware for url parameter firewall for Slim Framework 3.
Why we should create firewall for url parameter?
- To prevent from ddos layer 7 which is targeting to attack using random url parameters.
- To prevent useless webpage cache.
- To avoid BOT goes to wrong url.
- To hardening the CSRF and XSS attack.
- Etc.
So you better to whitelisting url parameter for each routes.

Open browser and now make a test:
http://yourdomain.com/ >> WORK
http://yourdomain.com/?page=1 >> WORK
http://yourdomain.com/?page=1&_=3123123 >> WORK
http://yourdomain.com/?product=test >> 404
http://yourdomain.com/?page=1&_=3123123&product=test >> 404
Note:
We should allow url param name _
