WebSockets Not Working Through Burp Proxy

Rahul | Last updated: Apr 04, 2020 11:25AM UTC

I'm currently performing penetration testing on a web application that uses WebSocket. I have the burp proxy correctly configured. I'm not able to intercept any WebSocket connection on any web application. What am I doing wrong here? I've gone through multiple blogs where they had suggested a couple of fixes. None of those fixes worked for me. Thing I've to enable : * disabling "Strip Sec-WebSocket-Extensions headers in incoming requests" *

Hi Rahul, Can you confirm the browser (and version) that you are using in conjunction with Burp?

Yes, I've tried it on both Firefox and Chrome latest version. Chrome: Version 80.0.3987.163 (Official Build) (64-bit) Firefox: Version 75.0 (64-bit) Operating system: macOS 10.15.4
