`X-Forwarded-Tls-Client-Cert` that contains the escaped pem. - `X-Forwarded-Tls-Client-Cert-Info` that contains all the selected certificate information in an escaped string. !!! info * The headers are filled with escaped string so it can be safely placed inside a URL query. * These options only work accordingly to the [MutualTLS configuration](../https/tls.md#client-authentication-mtls). That is to say, only the certificates that match the `clientAuth.clientAuthType` policy are passed. The following example shows a complete certificate and explains each of the middleware options. ??? example "A complete client TLS certificate" ``` Certificate: Data: Version: 3 (0x2) Serial Number: 1
