Gateway supports inspection of HTTP/3 traffic, which uses the QUIC protocol over UDP. HTTP/3 inspection requires traffic to be proxied over UDP.
Enable HTTP/3 inspection
To enable HTTP/3 inspection:
Gateway can inspect HTTP/3 traffic from Microsoft Edge, as well as other HTTP applications, such as cURL.
The following browsers do not support HTTP/3 inspection:
- Google Chrome
If the is enabled in Zero Trust, Gateway will force all HTTP/3 traffic in these browsers to fall back to HTTP/2, allowing you to enforce your HTTP policies. If the UDP proxy is not enabled, HTTP/3 traffic will bypass inspection.
Prevent inspection bypass
To prevent HTTP/3 traffic from bypassing inspection, disable QUIC in your users’ browsers.
