# Engine Editor > Add-Ons > HTTP/3 (QUIC) Inspection

Use this dialog box to activate HTTP/3 inspection.

Option | Definition
--- | ---
Include QUIC ports for Web Traffic | This option is enabled by default and activates QUIC inspection to the application traffic.
Discard HTTP/3 if Decryption is configured for the Connection | When this option is selected, any QUIC or HTTP/3 traffic that is configured to be inspected with decryption (TLS inspection) is discarded. As a result, browsers then typically fall back to using HTTP/2. Note: When configuring QUIC inspection it is recommended to select this option to ensure that traffic configured for inspection does not pass through uninspected. When configuring HTTP/3 inspection this option must be unselected.
