Incapsula provides the ability of sending the following information to the origin server:
- The TLS version used during the session between the end user and the Incapsula proxy. This information is sent via the INCAP-TLS-Version request header to the origin server.
- The Request ID which is assigned by the proxy for each request. This information is sent via the INCAP-Req-ID request header.
This can be enabled per site.
In order to enable the above request headers to be sent, go to: Site > Settings > General > Incapsula Headers, and choose the required headers.
