I am trying to configure BURP Tool. Following things i have done:

1) Ran web-application using tomcat port no : 8080, 2) Changed network to proxy 127.0.0.1:8080 in tomcat, and installed burp certificate in authorities 3) In burp tool, the proxy -> options -> intercept is running.

When i try to run my application i am getting following error message.

Invalid client request received: Dropped request looping back to same Proxy listener.

Can someone help me on this? Thanks in advance!!

I struggled with the same error. When I changed the port number to 8081 under Proxy Listeners in Burp (Proxy --> Options), it started working.

Is Tomcat running on the the same system as Burp? If it is, you need to use a different port number.

What URL did you enter to your browser? The symptoms you describe look like you used http://127.0.0.1:8080 - which points to your proxy. Instead, you need to enter the URL for Tomcat, e.g. http://mytomcat:8080
