Access-Control-Allow-Origin header doesn't exist

Richard | Last updated: Apr 26, 2021 12:31PM UTC

Hi, I am currently learning about CORS. When I accessed the Lab and saw the response in Burb Suite, I have seen there was no Access-Control-Allow-Origin header. I kept going with the solution provided in Michael Sommer's video, everything was OK, the Lab was solved. I went on with the next Lab, same thing happened. I wonder is there anything wrong with my Burp Suite? Is there any special set up? Please advise your guidance. Thank you. Richard
