• Domain: domain name of your original website, or hostname, or ip address, for example: www.chaitin.com
• Port: port that SafeLine will listen, such as 80 or 443. (for https websites, please check the SSL option)
• Upstream: real address of your original website, through which SafeLine will forward traffic to it

After completing the above settings, please resolve the domain name you just entered to the IP address of the server where SafeLine is located.

Then you can access the website protected by the SafeLine through the domain name like this.

Try to attack your website

Now, your website is protected by SafeLine, let’s try tp attack it and see what happens.

If https://chaitin.com is a website protected by SafeLine, here are some test cases for common attacks:

• SQL Injection: https://chaitin.com/?id=1+and+1=2+union+select+1
• XSS: https://chaitin.com/?id=<img+src=x+onerror=alert()>
• Path Traversal: https://chaitin.com/?id=../../../../etc/passwd
• Code Injection: https://chaitin.com/?id=phpinfo();system('id')
• XXE: https://chaitin.com/?id=<?xml+version="1.0"?><!DOCTYPE+foo+SYSTEM+"">

Replace chaitin.com in the above cases with your website domain name and try to access it.
