What's new
- Live highlighting in Proxy → Intercept. Intercepted requests are now colored in real time while they are held in the Intercept tab, based on the
x-mac-container-colorheader injected by PhoenixBox — previously the color only appeared in the Proxy HTTP history after the request was forwarded.
Details
- The container highlight color is applied at the
handleRequestReceivedstage. - The
x-mac-container-colorheader stays intact during interception (so you can still see/edit it) and is stripped before the request is sent to the target, as before. - Added test coverage for the receive-stage highlighting.
Compatibility
Built against Montoya API 2026.2; verified with Burp Suite 2026.4.x.
