This is totally random - This script does quick check for the external ssrf using multiple headers , you can also abuse this to send thousands of requests against random servers in the infra either external or internal (depends) as well as AC bypasses.
Note - "I know there is plugin like this in for burp but this randomized uniq id in burp collab to avoid any issues and keep sending and hitting the target(s)".
Note - you can also use 127.0.0.1 in place of id.collab.net to check for AC bypass.
python3 random_ssrf.py http://target id.collab.net '/endpoint'
#update - added more headers to rotate in order to detect dns/http interactions .
