How do I test an application using Server-Sent Events? I tried turning off 'Set "Connection close" on incoming requests in proxy options, but it seems like the streaming response data never gets into burp and never gets to the browser

Tony, have you tried using the Proxy > Options > Intercept Server Responses settings? - https://portswigger.net/burp/documentation/desktop/tools/proxy/options#intercepting-http-requests-and-responses Let us know if this helps.

I did try looking there, but it did not help.

Would it be possible to provide an example of the application?
