processHttpMessage and proxy tab

BitK | Last updated: May 04, 2020 08:14AM UTC

Hello, I'm developing a firefox/burp extension and where I'm adding a custom header to each request in firefox and stripping it in burp. This header is used to pass metadata about the request. This is working fine, but the request shown in the proxy tool is the request before the header was stripped, is there a way to show the modified request instead ? Or maybe the "auto-modified request" tab ?

Hi The proxy history will show the unedited request. If you use a third-party monitoring extension like Flow or Logger++, you should be able to see the edited request. You could create a separate tab to go along with the raw, params, headers, and hex tabs to display your stripped request?

Ok thank you, I'll leave it as this for now. Also when I was trying to do inter addons communication I noticed that burp catch all request with location http://(.+\.)?burp/. It would be nice if an addon could register a register subdomain like http://addon_name.burp/ and be able to catch all request without them being displayed in Proxy tab. I would allow addons to have a communication channel with the outside world without flooding the proxy tab.

Hi Could you provide some more information on the functionality you are trying to implement? Are you making a feature request, or trying to write an extension to achieve this functionality?
